Features
• Gas circulation, motor cooling and oil
behaviour are improved on light commercial
platform models by a new patented motor cap
design.
• Part protection and assembly reduces internal
leaks and increases life durability.
• Improved part isolation reduces greatly
acoustic levels.
• Gas intake design induces higher resistance to
liquid slugging.
Heat shield that lowers the heat
transfer between discharge and
suction gas and the acoustic level
New PTFE spring seal for even
lower leaks
R410A optimised and dedicated
scroll profile
Liquid slug protection per suction
fitting in upper position
Improved lower bearing centring
Patented motor centring spacer
Patented motor cap
WSH range is composed of WSH090-105-120-
140-161-184 which is based on current SH
range light commercial platform. The WSH
range benefit from a further improved design
to achieve the ~5% higher efficiency for low
pressure ratio applications such as water cooled
chiller, air-to-air rooftop etc...
