To achieve high combustion efficiency and deliver savings of over 35% in heating costs versus conventional forced air or hydronic systems, the Schwank STS-JZ Infra-Red Tube Heater couples our patented ceramic burner head with a powerful direct-drive blower located in line behind the burner. This system ensures a homogeneous gas-air mixture for optimum combustion efficiency and a long narrow flame, which is ideal for tube firing.

The power burner forces heat down a heavy steel tube with special emissive coating on the outside, which in turn radiates high efficiency infra-red energy. The unique Schwank Focus Shield Reflectors mounted over the tube direct the infra-red rays, like the rays of the sun, to the floor and the people below.

Depending on burner ratings, the technique provides low intensity radiant heat over a variety of tube lengths and configurations.

Standard infra-red tube heaters produce a 2' to 3' flame. Schwank infra-red tube heaters produce a 14' flame. As a result Schwank infra-red tube heaters deliver more even heat and are far more energy efficient than competing products. The flame shown above is produced by a Schwank STS 155 (155,000 BTU).

Flexible layout

A sample layout of an STS-JZ series tube heater system assembled from 10 ft. lenghts, U-shapes and 90o bends A- Flue vent through wall or roof B- Flue vent through common TEE C- Optional combustion air intake from outside

Can be readily assembled to suit any business shape and meet almost any heating requirements with nine different BTU sizes up to 200,000 BTU for either natural or propane gas.

If it is found during installation that it is desirable to bring in combustion air from the outside of the building, this can be accommodated at the site with standard parts supplied. No optional parts need to be ordered.

Tube lengths range from 10 ft. to 70 ft. and come in 10 ft. lengths with quick mount couplers for rapid assembly right out of the carton.

The system can be installed in straight form, U-shape with 180 degrees bend or with one or two 90 degrees bends.

Installation can be done in a vented or unvented mode. Flue venting is possible through side walls or the roof of the building, individually or through a common TEE.

Focus Shield Reflectors

This is another Schwank exclusive feature that is used to reduce the angle of dispersion of the infra-red rays and to concentrate rays to specific floor and work areas.

Reflectors can be positioned at settings ranging from horizontal to 45 degrees for highly focused heat delivery.

They have a large surface area and protrude well below the tube to enclose convection heat around the tube in order to increase infra-red efficiency.

Closed reflector ends

Closed ends stop convection heat escaping through the ends of the reflector and ensure reflector placement and stability.

Instant service access

There are no panels or doors to remove for service access.

The fold-away housing opens to expose all the controls and the burner for easy servicing.

The burner can be serviced from the end or the bottom.

Contaminated air is no problem!

A standard collar on the blower inlet permits the attachment of a combustion air inlet duct from any direction allowing the heater to operate using fresh outside air only. This makes the unit ideal for use in contaminated atmospheres.

Best warranty in the industry

It is covered by a replacement parts warranty that is unique in the industry: ten years on the burner cup and tubes; three years on all other parts.
