Stopfreeze Protection From Intertronics

Although primarily focused on boiler condensate discharge lines, both the STOPFREEZE KIT and STOPFREEZE COMBI, which feature an IP67 weatherproof in-line thermostat with integral LED indicators, can both be used for a number of pipe frost protection applications such as farms, caravan parks and camp sites, stables, lofts, garages, holiday homes and lodges, nurseries, outbuildings and sheds etc.

Given the often arduous environments the engineers at Intertronics recommended their IRS3071 which is a semi-rigid, room temperature curing, flame retardant polyurethane resin system. It is specifically designed for the cost effective encapsulation of a variety of low to medium voltage electrical and electronic applications. The system offers medium viscosity, flame retardation to UL94 V-O at 6mm and excellent adhesion to a wide range of substrates. IRS 3071 is resistant to UV, water based cleaning chemicals, motor oil, lubricants and most dilute acids and alkalis.

Paul Whitehead, Technical Manager at Intertronics, described their thoughts: “IRS3071 was suggested because it is a cost-effective way of environmental protection and void free encapsulation. It has the added benefit of adhering to the enclosure making it difficult to disassemble the enclosure without damage.”

Explained Neil Fairburn of STOPFREEZE manufacturers Eltrace: “We were looking for a potting system that was going to be superior to others used in the industry while being easy to use so that we could ensure consistently high quality, performance and reliability. The Intertronics system has been key to market acceptance of our STOPFREEZE in-line thermostat kits and allowed us to offer a simple and inexpensive solution especially suited to the residential market.”
