Chinese wholesale TU-1D091 thermal wax actuator for industrial thermostatic water regulations mixing valve to Toronto Factories Detail:
1. Operation Principle
The Thermostatic Wax that has been sealed in shell body induces expansion by a given temperature, and inner rubber seal part drives its handspike to move under expansion pressure to realize a transition from thermal energy into mechanical energy. The Thermostatic Wax brings an upward movement to its handspike, and automatic control of various function are realized by use of upward movement of handspike. The return of handspike is accomplished by negative load in a given returned temperature.
2. Characteristic
(1)Small body size, occupied limited space, and its size and structure may be designed in according to the location where needs to work.
(2)Temperature control is reliable and nicety
(3)No shaking and tranquilization in working condition.
(4)The element doesn’t need special maintenance.
(5)Working life is long.
3.Main Technical Parameters
(1)Handspike’s height may be confirmed by drawing and technical parameters
(2)Handspike movement is relatives to the temperature range of the element, and the effective distance range is from 1.5mm to 20 mm.
(3)Temperature control range of thermal wax actuator is between –20 ~ 230℃.
(4)Lag phenomenon is generally 1 ~ 2℃. Friction of each component part and lag of the component part temperature cause a lag phenomenon. Because there is a difference between up and down curve of traveling distance.
(5)Loading force of thermal wax actuator is difference, it depends on its’ shell size.

Here is my prototype for a fan control system based on Arduino. The idea is to maintain a constant temperature by controlling the speed of a fan by changing its supply voltage.
It is still a work in progress and I do not have a schematic yet, but the control algorithm itself seems to work very well already.
The test bench uses a paper box, a hot glue gun as a heat source and an old 8cm 12V PC fan.
It uses a PID (Proportional-Integral-Derivative) control algorithm to calculate the adequate power % to apply to the fan, through a PWM controlled MOSFET.
Once stabilized, the temperature is kept within a 0.1ºC error, and a stable fan speed.
The motivation was to design a system to maintain just the right temperature at the back of an absorption fridge in the summer by using just the right fan speed to avoid noise. It can be used in any forced ventilation application though.
