China wholesale TU-1D091 thermal wax actuator for industrial thermostatic water regulations mixing valve for South Korea Manufacturer 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.

Rik Kretzinger grew up on a Christmas tree farm and spent his college years studying horticulture, but he found it too difficult to make a living as a small farmer so he spent most of his career working for others.
A few years ago, he began to tinker with aquaponics (fishfarming + hydroponics), sensors and the open-source microcontroller Arduino to create an automated garden that could compete with commercial farms.
For the first couple of years he spent thousands of hours struggling to learn programming languages to automate his backyard mini-farm. Then while speaking at an international conference (along with Eric Maundu and Rob Torcellini, he’s among the elite few experimenting with aquaponics and automation) he was introduced to APDuino(open-source firmware for aqua- and hydro-ponics).
APDuino allows Kretzinger to read the sensors in his garden without any programming. Now Kretzinger’s garden can send him tweets or Facebook updates if something is going wrong and Kretzinger can adjust the water flow, pH and temperature from a smartphone.
Now, what started as a hobby may provide Kretzinger with the boost to compete as a small farmer. His plan is to keep it urban (or suburban). He’ll use unused backyards or vacant lots to grow his produce and he’s created a prototype tower (PVC structures similar to those in our videos of Rob Torcellini’s greenhouse and of rooftop hydroponics on Manhattan restaurant Bell, Book & Candle).
His towers can be removed and taken to farmer’s markets where customers can “pick” their strawberries or lettuce directly from the units. His set-up is also highly mobile so if a property owner decides he wants his land back, Kretzinger can move within a week.
