| Positive pressure low intensity tube heaters with TISS  A line of positive pressure low intensity infrared tube heaters has been introduced by Space-Ray with a patent-pending Innovative Tube Integrity Safety System (TISS) that provides additional safety for building owners. Available in both natural and propane gas, the new PTS/PTU Series Tube Heaters from Space-Ray use positive pressure to push products of combustion through the heavy-duty calorized aluminized or alumatherm steel combustion chamber. The heat exchangers are available in heavy-duty hot-rolled steel or as an ALC option in calorized aluminized steel for high humidity/corrosive environments.The heaters come with a choice of one-stage or two-stage input controls for added flexibility and a totally enclosed burner box that places all the power, thermostat and gas connections in one central location for easier installation and maintenance. By being fully enclosed, the noise level of the heaters is below 60 dB(A), making the heaters ideal for applications where minimal noise is desired. CSA-Certified, the tube heaters are available in eight models and over 100 different configurations for maximum flexibility in custom designing an infrared heating system to precisely meet individual building heating requirements. Capacities for the PTS/PTU Series range from 40,000 BTU/hr to 200,000 BTU/hr. The PTU Series is designed for use mainly in high heat loss areas and for spot heating while the PTS Series is designed for use in general building heating applications. The heaters are ideal for retrofitting existing push through systems and are certified for vented (sidewall or through the roof venting) or indirect vented operations, depending on application requirements. Applications for the new PTS/PTU Series Tube Heaters are varied and range from industrial plants and warehouses to aircraft hangars, machine shops, weld shops, maintenance facilities, automotive body shops and dealerships, fire stations, restaurants, sports facilities and greenhouses, farm buildings or dairy barns, waste water treatment plants, car washes and many others. With the TISS system, an insulated wire is placed above the reflector. A low voltage circuit control continuously monitors the clearance between the reflectors and the ceiling for excessive heat and tube integrity compromise. If the heat increases due to heat exchanger failure, the wire melts, the safety circuit is broken and the gas controls shut down. Also unique to the PTS/PTU infrared heaters is a totally enclosed burner box that includes the blower motor, heavy-duty cast iron burner and other features standard with the PTS/PTU Series heaters. These standard features include an outside combustion air collar for added flexibility, external 24 Volt thermostat connection and a three prong power cord connection to minimize installation cost. Also standard within the box are a step opening combination gas valve for quiet operation and added safety, a ½-inch MPT gas connection and monitoring light systems for trouble shooting in case maintenance is required. A 36-inch long stainless steel gas connector is shipped as a standard option with the PTS/PTU Series Infrared Heaters. Since the combustion chamber is totally enclosed, draft hoods are not required. A heavy-duty ball bearing blower motor comes permanently lubricated to reduce maintenance and does not require any lubrication for the life of it. write your comments about the article :: © 2008 Construction News :: home page |
