Space-Ray Expands Line of Low-Intensity U-Tube Heaters



CHARLOTTE, North Carolina - Space-Ray has expanded its line of energy-efficient, unitized low intensity gas-fired U-tube heaters to 21 different models, with capacities from 40,000 to 250,000 BTU/hr to meet a variety of industrial and commercial application needs.

The heaters are ideally suited for high air change environments and higher ceiling heights to help create an efficient and comfortable atmosphere for employees and customers. Applications 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 plus others.

Available in both natural and propane gas, the expanded line of Space-Ray LTU series low-intensity U-tube heaters are designed to save fuel and reduce maintenance. The heaters are well suited for mounting heights of 12ft. and higher, based on burner capacity. Some large capacity heaters have been installed successfully as high as 85' above finished floor. Length of the heaters is from 17.0 to 27.5 ft

C.S.A. design certified for horizontal and vertical venting, the heaters can be horizontally mounted for a maximum 75 ft sidewall venting capability instead of the normal 15-ft sidewall venting in most other units. Heaters can be either vented, common vented or indirect vented based on application requirements.

The heaters incorporate many features not found on most competitive units, including a unique self-contained heavy-duty draft inducer which pulls products of combustion through the heavy-duty calorized aluminized steel combustion chamber for increased radiant efficiency, greater safety and a more uniform tube operating temperature. The draft inducer is permanently lubricated and fan-cooled. A heavy-duty ball bearing motor assures maintenance-free operation.

Other features include a factory pre-assembled tube and reflector body with quick six-bolt control box assembly for easier on-site installation; a unique monitoring light system for on-line diagnosis and simple, easy maintenance; a state-of-the-art step opening redundant combustion gas valve for quieter ignition and added safety; a closed combustion chamber design for safety; and direct spark ignition with 100 percent shut off safety-control valve.

The reflector design of the heater totally covers the emitter tubes for a more uniform energy distribution at the floor level, maximum emitter tube temperature and minimum convection loss and no exposed U-bend.

Factory assembled on the tube body, reflectors come with easy-to-use mounting brackets. The U-tube design of the heaters with its large radiating surface also optimizes heat distribution.

The rugged one-piece cast-iron burner comes with a 10-year limited warranty. The calorized aluminized steel emitter tubes do not peel or flake, assures uniform tube temperature for long life, and produces high radiant efficiency. It comes with a five-year limited warranty.

In contaminated atmospheres or high humidity areas, optional outside air for combustion can be supplied with a standard 6-in. round duct. The LTU series is also C.S.A. certified for up to a 50-ft. outside fresh air inlet duct.

"These heaters have features not available on most competitive units that add flawless operation, low maintenance and fuel efficiency" noted Bob Genisol, Vice President of Space-Ray. "With its expanded line, Space-Ray offers among the broadest and most complete line of tube heaters in the industry that fit most industrial and commercial applications. We have over 200 different heating configurations to choose from to exactly match the need of our customers."

Space-Ray has manufactured gas-fired infrared heating systems since 1958. Like the other Space-Ray radiant tube heaters, the new expanded series offer fuel economy and radiant efficiencies unsurpassed by many competitive systems. Annual fuel savings of as much as 50 percent compared to forced-air heating, have been achieved by Space-Ray tube heaters. Some Space-Ray customers report fuel savings as high as 70 percent with a payback in less than one year.

Unique, unitized and pre-assembled design allows lower installation costs, simpler re-arrangement within the facility and less maintenance. By not being dependent on other heaters in the system, Space-Ray's infrared tube heaters can also be thermostatically controlled, individually or in groups, for greater operating control of heating requirements.

Unlike forced-air heating which works from the top down, radiant gas heat works from the bottom up, warming people, floors, and machines first for optimum comfort.

The first U.S. manufacturer to design unitized tube heaters, Space-Ray has over 47 years of field experience and exposure to industrial heating and commercial heating problems,

Besides the expanded line of LTU infrared tube heaters, Space-Ray also offers a complete line of LTS series low intensity tube heaters, 16 ETS/ETU low intensity tube heaters, a complete line of ceramic heaters, and radiant floor heaters. The company also offers an exclusive computerized heat loss analysis free of charge to qualified plant managers, contractors, and building owners.

Headquartered in Charlotte, North Carolina, Gas-Fired Products also has a wholly owned subsidiary in Ipswich, England.
