Q)
|
What are the differences between a MC/LC unit and a GM
unit?
|
|
A)
|
Both are air cooled units. The MG "Blue Star" units
have 2 condenser fans, MC/LC "Optyma" units a single
fan (except in sizes 215, 242 and 271 which have 2 fans).
This provides a choice of format to suit differing site circumstances.
The Optyma units are primarily designed for R404A or R507,
whilst the Blue Star are for R404A, R507, R134a and R407c.

Q)
|
What is the difference between the S10 and the S14 versions
of the MG "Blue Star"?
|
|
A)
|
S14 versions have provision to fit a pressure relief valve
to the liquid receiver. They also use flexible hose for the
pressure lines connecting the high and low pressure switch
to the system. (S10 units use copper pipe). S14 models up
to and including the MG28 and LG28 are also fitted with a
larger capacity liquid receiver. The pressure switch on both
S10 and S14 versions is auto reset on the low side, manual
reset on the high side.

exchangers as the condensers. They are fitted with HP/LP switch,
electrical box, liquid receiver and a two way pressure operated
water regulating valve (a three way valve for pump re-circulated
water is optional). The range up to WM80 are supplied in a
fully housed form.
