| Product List |
Q830 dual pressure switches are for use on commercial refrigeration
and air conditioning systems to protect compressor against
excessively low suction pressure or excessively high discharge
pressure.
Dual pressure switches are compatible with HCFC and non-flammable
HFC refrigerants.
Dual Pressure Applications are designed primarily for use as combination high and low pressure controls on commercial refrigeration and air conditioning applications.These controls are available in several pressure ranges and are compatible with most common refrigerants. Ammonia compatible models are also available.
Q830 series dual pressure controls can be not only used in fluorinated refrigerant, but also in the air
and liquid (allowed liquid temp. -20 to 120°C)
Adjustable range and differential settings.
Renovated SPDT micro-switch ensures the reliable switch function.
Flexible mounting bracket suits various kids of application.
Upper lid is optional (IP44)
Various connections are available on request.
Automatic and manual reset version
The material of bellows is copper and pressure interface is brass.
