It’s often said that any company’s greatest asset is its people, and this definitely is true for refrigeration contractors. Sure, the refrigeration industry is heavily focused on products and equipment and technology. And don’t forget chemicals – trying to keep track of all the refrigerant changes is enough to make anyone’s head spin. Yet if equipment is the lifeblood of the HVACR industry, then the people at refrigeration companies are its beating heart. And it clearly is in your best interest -- as the contractor whose name is on the door and on the trucks -- to keep your people as happy as possible.
Of course, reclaimers can only reclaim what contractors and technicians recover, and while the R-22 numbers may never match the hoped-for projections, the industry is already looking to the future and preparing to address new challenges in a post-hydrochlorofluorocarbon (HCFC) world that also is likely facing a phasedown of hydrofluorocarbons (HFCs).
This refrigerant leak sealant features a triple-power sealant that installs in just seconds. It features a push-button product flow valve that does not require a propellant or other such tools, thereby eliminating the need for technicians to carry multiple items, such as manifold gauges, caulking guns, screw drivers, and refrigerant hoses.
The Green Tech Line of refrigeration and air conditioning components is designed for use with natural refrigerants R-290 (propane), R-600a (isobutane), and R-744 (CO2). These high-quality, hydrocarbon (HC) and CO2-ready system components include valves, controllers, transducers, filter driers, and microchannel heat exchangers.
These units feature a 70°F floating head pressure control valve and an integral subcooling circuit that allows saturated liquid to flow from the receiver to the condenser where the refrigerant is sub-cooled by ambient air.
