R-290 Refrigerant Manufacturer,Supplier and Exporter in India
Product Code : EL-MWLE-13032
Jlab Export is a leading R-290 Refrigerant Manufacturer,and suppliers in India
Propane, sold for refrigeration as R-290, runs bottle coolers, ice cream freezers, display cabinets and some small split air conditioners. This pack is an 11 kg non-refillable cylinder for a workshop or training lab that charges several systems. R-290 is a hydrocarbon in safety class A3, so it is highly flammable, and it works at higher pressures than isobutane.

Charging Practicals for R-290 Systems
A typical sequence starts with a pressure test. Students fill the circuit with dry nitrogen from a Nitrogen Pressure Test Kit and note whether the gauge holds. They then evacuate with Fast Vacuum Pumps, which carry a built-in vacuum gauge, and break the vacuum with refrigerant.
The cylinder stands on a Wireless Refrigerant Charging Scale, so the charge is metered by weight against the rating plate. Hydrocarbon Manifold Gauges have an R-290 scale, so students read evaporating and condensing temperatures straight off the dial. A Split Air-Conditioner that runs on R-290 gives a full-size system for tracing the circuit. At the end, students recover the charge with a Combustible Gas Recovery Machine before the circuit is opened.
Frequently Asked Questions
Can R-290 be charged as vapour?
Yes. Propane is a single compound with no temperature glide, so vapour taken from the cylinder has the same make-up as the liquid. Vapour charging into the suction side is slower but gentler on a small compressor.
Do I need special tools for R-290?
Use manifold gauges with an R-290 scale, a recovery machine rated for flammable refrigerants and a leak detector that senses hydrocarbons. Keep power tools and extension leads that can spark away from the work area.
How should the cylinder be stored and moved?
Store it upright and secured in a cool, ventilated area, away from heat, flames and electrical switches. Move it with the valve closed, and never refill a non-refillable cylinder once it is empty.
How is an R-290 system opened for repair?
Never unbraze a joint on a charged system. Recover the propane with a machine rated for flammable gases, purge the circuit with dry nitrogen and cut the tubes with a tube cutter. Braze only once no refrigerant remains in the circuit.
