KPU - Pressure Switches
KPU pressure switches are designed to be contractor friendly and used in refrigeration and air-conditioning systems to protect the systems
from excessively low suction or high discharge pressure. They can also be applied to start and stop compressors and the fans of air-cooled
condensers. KPU pressure switches, in single and dual versions, cover a comprehensive range of applications and are designed for use with
Fluorinated and non-aggressive refrigerants. Most KPU pressure controls can be used with R-410a systems with only a few code numbers.

The Robertshaw® 780 Series Direct Spark Controls are applicable to commercial cooking equipment, gas fired heating, and water heating systems of many types. The system acts on a demand for heat by a switch or thermostat to open the gas valve. At the same time, the 780 series ignition control supplies a spark to the electrode which ignites the gas. After the gas is lit, an electronic circuit proves the presence of flame using flame rectification. When the thermostat is satisfied, the gas valve will be closed to shut off the main burner gas.

Features and Benefits
Replaces one rod and/or two rod systems
Easy-to-install with complete in-depth installation instructions
Reduces truck stock inventory, saving space and money

Robertshaw® thermopiles are the industry leader for gas appliance applications. Their primary function is to ensure a standing pilot light is operative so that on a call for heat, the main burner gas will be properly ignited. Thermopiles are placed in gas applications to detect the existence of a flame for safety purposes by shutting off the potential gas flow to a burner. A thermopile is the assembly of many thermocouples to increase the millivolt output. Robertshaw thermopiles have two types of connections: coaxial and two-wire spade connectors.

The 1950 thermopiles, also known as TP-75, are two-wire spade connectors. The 1951 thermopiles, also known as CP-2 (500-600 millivolts) are coaxial connectors.

The 1950 and 1951 Series Thermopiles (pilot generators) are designed for use on self-powered gas control systems. They can be used to replace similar competitive devices.

Features and Benefits
Easy burner installation with attached threaded nut
Stainless steel outer jacket for long life and resistance to heat blistering
Combination of copper and nickel alloys for good electrical conductivity
Mica washer to insulate from shorting conditions
Various lengths available for multiple applications
