Product Description
If you’re looking for an inexpensive way to protect your sensitive air system from potential danger due to impending fire, the FireChek is the answer. The FireChek will not only vent the pneumatic actuator, but it will also close the actuator air supply line when it determines the temperature has risen and there is a potential for fire. Since heat, not flame, is the trigger to shut down the air supply, the FireChek is superior to the traditional plastic tubing burn-through products. The shape memory element is extremely reliable and has been utilized for years in numerous industries, including the military. This product offers manual reset that makes it easy to test for safety and standard maintenance.
