Discharge Line Ball valves Discharge line ball valves are fitted to ensure ease of maintenance during shut
down periods.
Liquid Line Ball Valves Liquid line ball valves are fitted to ensure ease of maintenance during shut down
periods.
Filter driers Filter driers are fitted to ensure that the expansion device is protected from any
potential contaminants in the system. This can be serviced with changeable inner
cores.
Sight Glass A liquid line sight glass is fitted to give an indication of the state of the refrigerant
within the system. If the sight glass becomes yellow
it’s an indication that the filter
drier requires changing.

Switches HP / LP Transducers and switches are fitted to the unit to protect against high or
low pressures.
Electronic Expansion Valves
(EEV)
Electronic expansion valves differ to the normal thermostatic expansion valves in
their ability to maintain control of the suction superheat at reduced head pressures.
This can lead to significant energy savings particularly at reduced loading and low
ambient temperatures.
