This stainless steel solenoid valve is ideal for ammonia, but can also control CO2, fluorinated refrigerants, glycols, pure water, light oils, and other approved liquids.

This close-coupled, horizontal, end suction pump is designed for service in general pumping, chemicals, wash systems, deionized water, process, and OEM applications. It is designed for long life in tough services with flows to 240 gallons per minute (GPM). 

This zone valve is for use in hydronic heating and other HVAC systems, such as those with fan coils and air handlers. The mechanical valve allows one actuator to accept input voltages between 120 and 277 vac 50/60 HZ. 

These power blocks are rated 175 A and 600 V for electrical applications in power panel distribution. The blocks can also be used for lighter power applications and, therefore, have extended utility as a one-size-fits-all product line.

Bob and Tim are on a service call on a really cold and blustery day. The temperature is 27°F, the wind is blowing, and it’s snowing and sleeting. When the customer called, she said that their home is getting cool inside, and their heat pump is running all the time with the temperature dropping inside the house. They arrived at the front door, talked to the homeowner, and decided to look around. They went to the closet where the indoor unit for the heat pump was located and determined that the heat pump itself was not running, only the fan and strip heat.
