Hydrocarbon Manifold Gauges Manufacturer,Supplier and Exporter in India
Product Code : EL-RACLE-12741
Jlab Export is a leading Hydrocarbon Manifold Gauges Manufacturer,and suppliers in India
This manifold gauge set is made for refrigeration systems that run on hydrocarbon refrigerants. Its 80 mm gauges carry temperature scales for R-600, R-600a and R-290, the butane, isobutane and propane gases used in many domestic refrigerators and small cabinets. A sight glass shows the flow through the manifold, and the three 120 cm hoses have 1/4 in ends.

Workshop Practice on Hydrocarbon Systems
On a Domestic Refrigerator that runs on R-600a, students connect the blue hose to the low-side access valve. The yellow hose goes to one of the Small Vacuum Pumps. They evacuate the system, watch the blue gauge fall into vacuum, then close the valves to see whether the vacuum holds.
For charging, a can of R-600a Refrigerant stands on the High Precision Charging Scale, which reads to 1 g. Students feed vapour into the low side and stop at the weight on the rating plate. They then read the suction pressure against the R-600a scale to find the evaporating temperature.
Frequently Asked Questions
Can this set be used on R-134a or R-22 systems?
The hoses will connect, but the temperature scales read only for R-600, R-600a and R-290. For R-134a, R-22 or R-404A work, a set scaled for them, such as the Manifold Gauges For Refrigeration Systems, gives the right saturation readings.
How do I read the evaporating temperature?
Read the low-side pressure, then follow the needle to the ring for the refrigerant in the system, such as R-600a. That ring gives the saturation temperature at that pressure. Compare it with the pipe temperature at the evaporator outlet to work out superheat.
What does the sight glass show?
It lets you see what passes through the manifold body while charging or recovering. Clear liquid, bubbles or mist show whether liquid or vapour is moving, which helps you judge how the charge is going in.
Why are hydrocarbon systems charged by weight?
They hold a small charge, so a few grams over or under changes how the system runs. Gauge pressure alone cannot tell you the amount inside. Weigh the cylinder while charging and stop at the figure on the unit rating plate.
What safety steps apply to hydrocarbon refrigerants?
R-600, R-600a and R-290 are flammable. Work in a ventilated area away from flames and sparks, pressure-test with dry nitrogen rather than refrigerant, and close the cylinder valve whenever it is not in use.
