Thermal Charge-Check Refrigerant Charging Cylinders
• Available in light domestic to heavy-duty commercial applications.
• Allows measuring precise quantities of refrigerant.
• Helps speed up the charging process by letting you charge with heat.
All cylinders except the 16 oz models will hold a model 55-7020 heater
assembly.
• Allows you to carry small quantities
of refrigerant to the job, yet buy
refrigerant in large quantities and
keep the drum back at your shop.
• Available in a steel carrying case to
completely protect from tough use.
Cylinder need not be removed from
the case as all connections and
valves are accessible from front.
Case forms a stand to set on the floor
or bench.
• Easily used in the field. Unit can hang
from system being charged by means
of a top-mounted bail.
• Can be calibrated for ambient
temperature variations by means of
temperature correction chart on the
side of the scale. This is required only
if better than 2% accuracy is required.
• Safety relief valve for protection
• Plastic liquid level indicators
