Thermostat

for Industrial Refrigeration

KP

The KP Thermostats are single-pole, double­throw (SPDT) temperature-operated electric
switches.

They can be connected directly to a single-phase
AC motor of up to approx.
2 kW or installed in the control circuit of
DC motors and large AC motors.

The KP Thermostats are used for regulation, but
can also be seen in safety monitoring systems.

They are available with vapour charge or with
adsorption charge.
With vapour charge the differential is very small.
The KP Thermostats with adsorption charge are
widely used to give frost protection.

Features • Wide regulating range

• Can be used for deep freeze, refrigeration
and air conditioning plant

• Welded bellows elements mean increased
reliability

• Small dimensions.
Easy to install in refrigerated counters or
cold rooms

• Ultra-short bounce times.
This gives long operating life, reduces wear to
a minimum and increases reliability
