ELECTRICAL CONTROL & ELEMENTS

 
REX 410

Please read Postage

  All postage is for the UK.   Europe and the Republic of Ireland is International postage no longer available. However, if items are under 2Kg I can send them with Royal Mail as customs is not such a problem this is still an option for small items.

Electrical Control features the Rex 410 will control more or less anything to the specific temperature you set it at. It will hold this temperature forever unless you change the setting or switch it off.

These are best suited to small loads. i.e. a few watts as they operate as an on-off switch. This means they switch on and off at full power.  If you have a 3/4/5/6Kw load that is the power it switches at. Industrial situations are fine. Domestic situations are not so as it will dip the lights for several houses around, not just yours.

For controlling a mash you only want a few watts they are brilliant as they will keep the temperature to the exact temperature you set them at. 

I have some 100-watt heating belts that fit the 30L plastic brew buckets a treat. I use them for my mash. In winter I wrap the buckets with bubble wrap and the heaters do not come on very often to maintain a 24ºC setting via the Rex 410 PID.

 Liquid Heating Elements

2Kw x 1” thread needs a 1.1/4” hole to fit the same again for the 3Kw x 1” element and the 4Kw element. These elements have a 1” BSP ‘G’ Thread. This is a straight thread as opposed to the BSPT thread which is a tapered thread. All elements come with a soft silicone gasket. Fit this on the outside against the nut of the element. Do the element up only just overhand tight. With a box spanner, it just needs to be hand-tight.

They are excellent for an on-spec fit to anything anywhere. You can fit them into your still pot or soup pot. You can weld in a 1” spud to your still and fit them there. You can just drill a 1-1/4” hole push the element in and fit a back nut. Jobs done. I can also make a terminal cover for these elements but I only supply it with the element as it has to fit that element. 

The new supply of elements also has a Thermo port built into the element. The 2Kw element is approximately 19cm long and the 3Kw element is approximately 22cm long. You can even fit them into a beer keg with a 1.1/4” hole and a little ingenuity. I also have some terminal shrouds that fit the live terminals to offer some protection but are not recommended if there are little children about the place. 

The terminal covers include a cable clamp and lock nut, an earthing stud with nuts and washers and a safety external dome nut. If you are fitting into an existing 1″ thread fine. If you are fitting into an un-threaded hole then you will need to order the backnut.

2Kw x 1″ BSP Element £16.50 20cm long.

   

3Kw x 1″ BSP Element £17.50 23cm long.

   

4Kw x 1″ BSP Element £18.50 27cm long.

   

1” Back nut £ 2.10 + p&p

   

Terminal Shrouds are not recommended if there are children around £1.00 per pair. Not necessary with a terminal cover.

   

The Terminal Cover is only sold with the element. £10.00 each extra plus the standard price of the element.

2Kw with cover £26.50 20cm long.

 

2Kw element with terminal cover and backnut £28.50.

3Kw with cover £27.50, 23cm long.

   

3Kw elements with terminal cover and backnut £29.50.

   

4Kw with cover £28.50, 27cm long.

 

4Kw with terminal cover and backnut. £30.50, 27cm long.

Tri-Clamp Elements. 

Again this is a 3Kw element but with a Tri-Clamp base. This means it is only suitable to be fitted to a tri-clamp base. ( Ferrule ) It does not have a thermo port. These elements will not fit the 2″ 64mm Bulkhead Fittings. These are only suitable for the normal 2″ 64mm Ferrule. 

I do have Tri-Clamp Elements that do fit the 2″ 64mm Bulkhead fitting be sure you choose the correct one.

2” 3Kw Tri-Clamp Ferrule Element 30cm long. £30.00

 

2″ 3Kw Tri-Clamp Bulkhead Element 30cm long. £30.00.

 

2″ 4Kw Tri-Clamp Element. Ferrule Fit 30cm long. £33.00

 

2″ 5Kw Tri-Clamp Element. Ferrule Fit 34cm long. Not suited to 50L boilers and below. Only suitable for 100L boilers and above. £37.00

 

The 4Kw and 5Kw elements can be used on single-phase and 3-phase electrical supplies. Just change the link system on the element terminals.

The elements can be controlled via a controller. This will regulate the current going to the element and so control the rate of the boil.

This can be made by yourself or I can make it for you. The parts are all available on the website. I can make it on your behalf for around £90.00 for a 3Kw controller.

 

 

 

 Ammeters

80 to 230 Volt AC. Amps 0 to 99.9 These are lovely items. Simple to fit simple to use. Drill a 22mm hole. Pop in the ammeter and tighten up the nut. Connect an AC supply to the screw terminals. Plugin the current transformer supplied. Pass the cable of the item you want to detect the current ( AMPS ) through the coil and that’s it.

 Ammeters £8.50

Green Ammeter

   

Blue  Ammeter.

   

Red Ammeter

   

Amber/Yellow

 

 
Red Indicator

LED Indicator lights. These are 230 Volt mains voltage led indicators. These are a perfect match for the Ammeters.

I only have Red at the moment. They are quite bright and fit a 22mm hole. Price £7.90

 

 

MCB Holder

A brilliant little item.  Fits all major makes of MCB. Make your rectangular hole in the panel,  box or whatever. Fit the MCB holder then fit in the MCB,  just clip the MCB support into place. The MCB is fixed securely into place.

This allows you to fit an MCB into anything. On / Off control with protection.

MCB Holder £4.00

   

Sorry about the P&P but most items are classed as small parcels.

Please also note that the MCB is not included

 
Contactors

Contactors are a Din Rail or similar Fit. But I am sure with a little ingenuity they can be fitted in a different way. These are a 2-pole 230 Volt coil single phase 40Amp contractor.  Ideal for the heating elements on sale on this site.

Price £25.95 + P&P

   

2 x 40Amp Contactors £48.00

 

 
Sight Glass Light Fitting

I make these especially for the 70mm OD and the 80mm OD sight glasses rims.

These will fit the weld-in, threaded and tri-clamp glasses of the above size.

These are all handmade and take a long time to make. If you don’t believe me try it.

They come complete with 2mts flex with a 13amp plug top attached.

A 50-watt 220volt GU10 lamp holder and lamp.

Website price £66.00 for the light fitting only.

70mm Light Fitting” £66.00″

80mm Light Fitting £66.60

 

 

ROTARY CAM SWITCH

3 Position Rotary Switch. These are 20Amp Change Over type switches ideal for just one element or the two together.  Left one position and Off in the centre-right for the second position i.e. two elements.

The terminals can be looped and configured to make that happen. If running elements that pulse on and off via a PID to maintain a set temperature then a couple of SSRs would be best to use. If you are using a constantly variable source of control that switches on and then varies the power to the elements while still constantly on then a contactor or two would be the best use.

Rotary Switch £14.85 

   

 

KEY SWITCH

These have 10 Amp Contacts but obviously, you don’t want to put 10 Amp through them. Run via a Contactor or SSR or similar. These are also made by the world-famous company Chint.

They are nice well made strong switches that retain the key when in the on position.

Key Switch Price £9.95 

 

 
Neutrik Connector.

I have a few of these connectors in two sizes.  4mm to 6.5mm and 8 to 12mm.  The small one is ideal for the probe lead that comes with the PIDs and the larger one is ideal for small cables up to and including 1mm 3core. The size is just nice for the supply of smaller items such as the 100-watt heating belts. These make perfect controls for the mash bucket when fermenting your wash to ensure the temperature stays perfect for the yeast. These connectors are really designed for a straight connection but they also lend themselves to being panel mounted. See Photo.

4mm to 6.5mm Neutrik Connector  £6.60 + P&P

   

8mm to 12mm Neutrik Connector  £9.30. + P&P

  

 
 
Electrical Controllers. 

Grey ABS box to make your very own electric element controller. They are easy to work with and are aesthetically pleasing. I use this box myself for my element controller.  Yes, it does involve some measuring and cutting but you don’t get out for nowt.

I make controllers for individual customers. I do not sell them on eBay.  A – they are very time-consuming to make.  B – eBay are greedy bugger, they would end up making more than me. I will be making some for sale on this website. Some will be the simple Rheostat type some will be the SSR type and some will be the PID  type controller. The Rheostat and SSR will have a cooling fan fitted. The price will reflect what goes into making the controller. The box measures 250mm x 190mm x 110mm this is an ideal size to customize.

You can buy a box.

   

You can fit your chosen additions and have a very nice controller. If you would like me to make one for you please get in touch. The one I make will have everything fitted all you will need to do is plug it into a mains socket and plug your element into the controller.

The basic box is £18.50 +P&P  The controller ready-made is £110.00  for the Rheostat type i.e. variable resistor.  The PID controller is complete with a 40amp SSR.£130.00 These units are all tested before I send them. All controllers I make incorporate a cooling fan. Keep your bits cool and they work better,  last longer, and work more efficiently.

For more info or something a little different please ask

Rheostat Controller £110.00

   

SSR Controller £115.00

   

PID Controller £130.00

   

6Kw SSR Controller No Sockets This needs to be wired in. £155.00

   

8Kw 230 Volt Stainless Controller £198.00   I now have in stock some Stainless Cabinets that I can now make into controllers. If this is something of interest please ask.

The ready-made SS controllers are made with two controls so you can adjust the temperature of each of the two elements. Being Stainless Steel it does not have a fan. £199.99

 

Just a little info for controllers 

40 amp SSR will run up to 9Kw of element @ 230 Volt.

60 amp SSR will run up to 13Kw of element @ 230 Volt.

80 amp SSR will run up to 18Kw of element @  230 Volt 

It is also important to remember that it is not advisable to run electrical equipment at its maximum if you want it to perform at its best with longevity with large resistive loads. Electric motors are another thing altogether.

I would say to get the best the load should be no more than three-quarters of the maximum output. 

 

Brew Belt

The belt can be supplied by itself with either the UK or Continental Plug Top.

It comes as standard with the two-pin plug. The UK 13amp plug top with a 3amp fuse fitted is extra. Standard Belt £5.00 UK Belt £5.75. The belt itself is approx.1mt long. This can be supplied as part of the PID Mash Controller.  The Controller is suitable for around 5amps of heating power. The belt supplied with the controller is 75 watts. Less than half an amp.

The controller comprises the PID and an SSR to supply the power to the heat belt. I do not fit a fan to this model as the load will never make things hot so cooling is not necessary.

The sensor can be taped to the mash bucket. Just slid the sensor threaded bolt out of the way. I use this myself and I set the PID to 24ºC so it is ready to go to work. You can easily adjust the temperature up or down by pressing the Set button until the LEDs flash and then press the up or down arrows until the temperature of choice appears and press the Set button again until the LEDs stop flashing. It is not advisable to go into settings as this can lead to all sorts of problems.

Brew Belt UK Plug Top £5.75

 

Brew Belt Continental Plug Top £5.00

 

Controller complete with PID, SSR and Belt all ready to go to work. £116.00 + P&P

 

Industrial Plug and Socket.

I now have a few Industrial Plugs and Sockets. 

These consist of the blue single phase 3 pin 16 amp and 32 amp. These are sold as a pair of One Plug One-Socket. The socket part can be surface mounted or mounted on a control box with the connection inside the box, just remove the surface mount supplied with the socket.. 16 amp is far better than the 13 amp.

16 amp plug and socket £9.80.

 

32 amp plug and socket £12.80.
