Pre-insulated pipework for air-conditioning and refrigeration

pipes
Preinsulated pipework for air-conditioning and refrigeration systems from Armacell reduce installation costs.
Pre-insulated pipework from Armacell can be supplied with SAE flare fittings and other accessories. Armaflex Split and Duosplit pre-insulated pipework is designed for single-split and multi-split air-conditioning systems, reversible heat pumps, refrigeration systems and cold shelves. The seamless drawn copper tube used is purged using nitrogen during annealing, giving a very clean tube with carbon levels well below current standards for refrigeration applications. The pipework is then pre-insulated with a closed-cell foam, which reduces the cost of installation. Further savings are achieved with Duosplit, which comprises two insulated copper tubes of different diameters (for refrigerant flow and return). These tubes are joined with a connection system that permits separation and re-joining without damage or the need for special tools. This insulated tubing is available on coils in a range of sizes.
