PROCESS CONTROL
REFRIGERANT CYLINDER JUG WARMING
Warm a refrigerant cylinder jug and maintain optimal temperatures for servicing during cold seasons
Application
Residential and commercial buildings rely on many forms of cooling
systems to keep people, animals, food, chemicals, etc. cool and
comfortable. The most common systems are air conditioning or
HVAC units, but there are also many refrigerators, freezers, and
dehumidifiers used. When these units are serviced, the refrigerant
gasses within the system must be removed and placed into a
storage tank, then cleaned to remove impurities and pumped back
into the unit.
Many HVAC units, walk-in refrigerators, deep freezers, etc. continue
to require scheduled and unscheduled service during the cold
season. The cold weather can cause unique problems for refrigerants
and service technicians. Cold weather causes the pressure inside
a cylinder jug to drop. At 0°F (-18°C), the pressure coming out of a
jug of R22 Freon ® is only 24 PSI. When the system being serviced is
running, the suction pressure will be near 60 PSI or greater. Prior to
servicing, the surface temperature of the cylinder must be elevated
to approximately 100˚F (38˚C) or greater to maintain adequate
pressure inside the cylinder.
Solution
BriskHeat’s HotBelt is an ideal heater for pre-heating and
keeping refrigerant cylinder jugs warm. The plug-and-play heaters
fit snugly around the cylinder to warm the contents so that
refrigerant gas can be effectively discharged during servicing.
The heaters have an adjustable strap to fit any cylinders with
diameters between 9 in (23 cm) and 13 in (33 cm). This fits the
most common sizes of 30 lb, 50 lb, and 125 lb cylinders. A built-
in controlling thermostat maintains cylinder surface temperature
at approximately 120°F (49°C). This ensures that the refrigerant
is kept at an optimal operating pressure for servicing.
The HotBelt heater is safe for indoor/outdoor use and grounded
for safe operation.
