We can manufacture individual temperature controllers as a request or complete control panels suppliers from a bench mounted panel to a fully mobile multi zone control panel. As the most basic form of automated temperature control, on/off devices often incorporate latching relay switches, which must be manually reset after they reach a specified shutoff temperature The RCD should be 30mA maximum and should be of good quality. There are many low cost & low quality ones in the market, which can cause problems without any reason Install the temperature sensor from the Clawhammer Supply controller into the thermowell. The temperature sensor will simply slide into the thermowell. The thermowell is included in our heating element adapter kit.

I will note that I am not an electrician but the wiring is very straight forward. I did a lot of reading here before taking on this endeavor which insured my success. Since 220v is essentially a pair of 110v hots, I was able to wire up a 220v outlet in my garage to run this thing by adding a dual pole 30amp breaker to my sub panel and then an outlet box with a L6-30R receptacle. For my application, I used C = 0.000330F (or 330 micro farad), R1 = 22000 ohm (or 22 kohm), R2 = 000 ohm (or 1 kohm), and R3 = a 100000 ohm (or 100 kohm potentiometer). With these values the "ON" time was 5 seconds per cycle. Based on the setting of the potentiometer, the "OFF" time ranges between 5.3 seconds and 28.4 seconds.All control panels are manufactured in-house, to suit our customer’s requirements.

Ceramic heating elements convert electricity into heat through resistive or joule heating. Ceramic elements boast a high energy efficiency by converting around 96% of the input power to heat to extremely high proportions. They are suitable for: These devices offer the simplest form of automated temperature control, and can only respond to the temperature crossing the setpoint one way or another A still can be heated with an electric hot plate, propane, or even over a fire. However, it is best to run stills with an electric heating element and a digital controller. When running a still with an electric heating element and digital controller there is no need to worry about filling a propane tank, open flames, or a hot plate cycling. The best thing about running a still with a controller is the ability to easily dial in the drip rate.

To combat this, they can be engineered to include hysteresis, which in practice means that there is a built-in buffer zone to prevent the device chattering between on/off within a range of safe temperatures This dial face for the above controller. This wasn't needed but i thought it added a finished touch to the enclosure while also giving me a visual point of reference on for the potentiometer that controls the power output. The RCD can trip when the Earth circuit of the building is not good enough. There is always a difference of potential difference (residual current) between Neutral and Earth coming from the Earth. This value increases with humidity and many other reasons. If the Earth connection is not good enough this will be added to the residual current generated by the electrical appliance and will often trip the RCD. The Clawhammer Supply digital controller is able to run in a set value mode as well as in manual mode. When running a still with a digital controller it is best to run the controller in manual mode. Read the directions on switching the controller to manual mode in this article. How to Use a Digital PID Controller to Run a Still

This is the control circuit that I designed for this project. It is based around a 555 timer IC. This configuration is known as " Astable Mode." In this mode, the output a pin 3 is a series of HIGH and LOW pulse. This turns the relay off and on. The frequency and duration of these pulses is determined by the values of the resistors and the capacitor. Installing the heating element adapter on one of our stainless stills is extremely easy. Attach the heating element adapter with a tri-clamp and gasket. The full video install is located here. Immersion heaters are usually found in water cylinders to heat water and heat the surrounding water in the cylinder, popular for heating failed boilers. Cut the cable to the desired length and strip the outer sleeve for approximately 40mm. Cut the coloured wires to the correct lengths and strip off approximately 5mm of the insulation on each one.
