Industrial Heaters

WAHLCO - Duct Heater

WAHLCO Duct Heaters are used to heat process air and gases up to 1200°F/650°C for forced-air applications, including drying, curing, heat treating, re-heating, dehumidification, and annealing. WAHLCO makes premium duct heaters that are typically used in crucial high temperature applications requiring long life.

Wahlco - Ammonia Generation System

WAHLCO’s Urea to Ammonia (U2A) generation system is a patented process that effectively converts urea to ammonia on site “on demand” and eliminates the transportation, transfer and storage of significant volumes of toxic ammonia. The U2A System basically reverses the process used to make urea. A urea solution is fed into a reactor, where it is heated under pressure to decompose to a gas mixture of ammonia, carbon dioxide and water vapor. This gas mixture is then piped to the point of use.

Wahlco AOD - Ammonia System

For small applications of up to approximately 30 lb/hr of ammonia, WAHLCO has developed a cost effective urea to ammonia system under the trademark: AOD (Ammonia on Demand). The technology offers a small packaged unit complete with urea feed pump, controls, ammonia production, and heated dilution air. All of the components are fully contained on one small skid to enable quick and easy installation.

Aqueous - Ammonia Systems

Aqueous Ammonia is a safer ammonia reagent for SCR applications than anhydrous ammonia; however it is more expensive on a delivered basis due to the large amount of water transported. Additionally in the case of 19% aqueous ammonia, there will be approximately five times as many deliveries as anhydrous ammonia. Operating costs are also higher due to the energy required to vaporize the water.

Anhydrous - Ammonia Delivery System

Anhydrous Ammonia is an economical reagent choice for utility SCR installations. The disadvantage of anhydrous ammonia is that it is classified as a hazardous material, and is subject to strict regulations and Risk Management Procedures for transport, storage, and handling. These requirements result in additional costs and complications in permitting and may generate local community concerns over transporting hazardous materials.

Wahlco - Flue Gas Conditioning Systems

Flue Gas Conditioning is WAHLCO’s traditional core business and the product line which formed the basis of the company’s founding. FGC systems allow coal fired boilers to burn a wider variety of coals, including lower cost high ash coals and low sulfur coals which avoid the cost of scrubber installations, without affecting the performance of the fly ash particulate collectors (electrostatic precipitators).
