Replacing Compressors in Water-Utilizing Systems:
Preventing Explosions
In certain water-utilizing refrigeration systems, water can leak into the refrigerant side of the sys-
tem. This can lead to an explosion of system components including but not limited to, the com-
pressor. If such an explosion occurs, the resulting blast can kill or seriously injure anyone in the
vicinity.
Water-utilizing systems that have single-wall heat exchangers may present a risk of explosion.
Such systems may include:
•
water source heat pump/air conditioning systems, and
•
water cooling systems such as icemakers, water coolers, and juice dispensers.
Water-utilizing systems that have single-wall heat exchangers present a risk of explosion unless
they have either:
•
a high pressure cut-out which interrupts power to ALL leads to the compressor or
•
an external pressure relief valve.
Before replacing a compressor in a water-utilizing system, read and follow “Prevention of Water-
utilizing System Explosions” on pages 6-7.
