Spiral Low Mass Radiant Tubing


Heat Treated Sprial Low Mass Radiant Tubing

This patented feature of the Reflect-O-Ray® and Omega II® systems increases the efficiency of our radiant tube systems. Our patented Low Mass radiant tubing heats up faster, allowing optimum radiant emitter output faster than any other radiant tube systems available.

Dry Tube System

Dry Tube system verses Condensing tube system

Combustion Research Corporation has always maintained that optimum efficiency is superior to maximum efficiency. This is important to the overall longevity of a radiant tube system. A radiant tube system that continuously produces condensate will increase thermal efficiency by as little as 2% -- however the effects of the extremely corrosive condensate will eventually destroy the radiant tubing. Prudent choices must be made. Disposal of this corrosive, acidic condensate into the community's drain system is not an environmentally sound choice. Heavy walled and glass lined radiant tubing will eventually fail, corrode, and require replacement -- the costs of replacement negate any savings that may have been realized. Combustion Research believes that systems that have "built in" maintenance is counter productive. An "Optimum" radiant tube system design incorporates the highest efficiency while maintaining low maintenance. This "Optimum" design gives the building owner the greatest overall cost savings. Reflect-O-Ray® and Omega II® have been engineered to deliver "optimum" results.

No Filters

No Filter, they equal added cost!

Reflect-O-Ray® and Omega II® systems are engineered so that combustion air filters are not required. When filters are not maintained, system failures can occur -- resulting in reduced system effectiveness and the increased potential for failure of the entire system. The constant replacement cost of filters only adds to the maintenance expense. After all, customers investing in a radiant heating system for their facility are looking to cut expenses.

Optimal Radiant Tube Length and BTU Input

The objective of a low intensity radiant tube system is to convert the highest percentage of gas-fuel into Infra Red energy. This Infra Red energy is absorbed by the building's concrete slab as well as the materials and items within the building. It is this absorbed energy that is stored and re-radiated to the interior of the building which provides the feeling of unparalleled comfort. In order for the building to absorb the optimum amount of energy, it is important to maintain an acceptable "Optimum Ratio of BTU Input to Radiant Emitter Tubing."

Radiant heating systems manufactured by Combustion Research Corporation have been engineered and designed with the emphasis for "Optimum Efficiency." Short radiant tube length, high input systems -- which have become prevalent -- conceal their additional operating costs. By reducing their tube lengths and increasing the BTU per hour input, the up-front costs are generally reduced. However, the trade off is lower system efficiency that requires additional BTU input to replace the wasted energy these short tube systems create. This in turn drives up the operating costs. Pre dilution exhaust temperatures in excess of 450° F have been seen. The exhaust temperature should not require dilution air for a well-designed radiant system. An "Optimum" radiant tube system will incorporate enough radiant emitter (tubing) which will deliver the maximum efficiency while striving to produce an effective "Optimum Ratio of BTU Input to Radiant Emitter Tubing."
