Space-Ray: POSITIVE PRESSURE LOW INTENSITY TUBE HEATERS WITH UNIQUE TUBE INTEGRITY SAFETY SYSTEM

Monday, August 11, 2008

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.   The TISS™ system is unique to Space-Ray.
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.
Unique TISS™ System and Heater Features
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.
“We decided that if we introduced a positive pressure system, that we would take steps to assure the integrity of the system and provide the ultimate in fire safety


protection for positive pressure radiant tube heaters,” noted Bob Genisol, Vice President of Space-Ray. “We wanted a system that was safer than what is available in the market today.  The TISS provides peace of mind.  It may never be needed but in the unlikely event of a tube heater failure you will be pleased that you have a TISS system”.
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.
Heaters Described
The PTS/PTU Low Intensity Tube Heaters are available with optional end, side, corner and U-Bend reflectors.


Lengths for both the PTS or PTU series heaters vary from 10 to 70 feet, depending on the model selected.
The heater’s highly efficient aluminum reflectors have a high reflectivity rating
of 97.5% for optimum efficiency.   The reflectors totally cover the emitter tubes for uniform energy distribution on the floor level, maximum emitter tube temperature and minimum convection loss.  Individual reflectors can be rotated up to 45o to direct the heat where needed. A heavy-duty reflector support hanger adds to the durability of the unit.
