PROCESS CONTROL HEATED HOSES FOR SPRAY FOAM INSULATION An efficient cost effective way to heat spray foam hoses Application Spray foam is a popular insulation alternative to traditional fiberglass materials. It is a two-component mixture (isocyanate and resin) that is typically stored in cylinders or small barrels. The liquid materials must first pass through two separate hoses that come together into an applicator gun that mixes the materials to form an expanding foam spray. Typically, these components flow best at temperatures above 70°F (21°C). If the components get too cold, they become difficult to extract and they don’t flow well through the hose and the applicator gun. This can result in slow production time or even clogs and damage within the system that can cause significant downtime. Solution Heat the hose with XtremeFLEX ® RKP silicone rubber heating tape. This super flexible heating tape is designed with a built-in pre-set thermostat that maintains heat output at 70°F (21°C). The supplemental heat ensures an optimum operating temperature is provided to assist spray foam components as they travel through delivery hoses and into an applicator gun. The RKP heating tape has a low watt-density of 6 W/ft (20 W/m) to provide safe operation and avoid overheating the chemicals. Standard lengths are available from 10 ft to 200 ft (3 m to 61 m) to meet your needs. If necessary, higher temperature, higher watt-density and custom length options are available. For added protection and efficiency, wrap the hose and heater assembly with an insulated abrasion resistant cover. This solution eliminates downtime and extends the service life of your spray foam equipment. Protect the cylinder or barrel with a BriskHeat DHLS Drum Heater. The DHLS drum heater is adjustable up to 160°F (71°C). Both heating solutions are easily installed and “plug-and- play” ready, allowing the warmers to be plugged into a standard electrical source without special wiring. Additional Uses BriskHeat’s RKP long-length silicone rubber heating tapes with built-in pre-set thermostats can also be used for freeze protection on complex winding or difficult-to-install pipe applications, or on objects that have unique shapes and sizes. Custom RKP heating tapes are available.
