Hygrex Technologies Inc
Toronto, ONTARIO (CANADA), Canada

HYGREX Industries has become todays' proven leader in dry air technology, by offering energy-cost effective, environmentally friendly, method of drying. HYGREX specializes in drying applications where water is basically the only element to be removed. Particularly suitable applications for dry-air generator include: drying food, filtercake sludges, water-based paints components, retrofit gas/heat ovens and the elimination of humidity in plant environments. HYGREX closed loop process 1/6 the energy cost of conventional drying methods. Buy using this closed-loop process the HYGREX dry-air generator does not require the installation of exhaust or air makeup, nor does it add heat to the material being dried, eliminated the risk of distortion, as well as cool-down zones and tunnels. No odours or gas emission are generated and the condensed water is reusable. HYGREX technology is currently in use worldwide in the following industries: food drying,automotive manufacturers, environmental companies, paint finishing systems, chemical companies, waterbased undercoatings, paint manufacturers, leather companies, drying toxic wastes, adhesives, agri-business. Applicable sectors include waste reductions, emission control and water recovery.

HYGREX-Spehr Industries specializes in drying applications where water is basically the only element to be removed. Particularly attractive applications for the dry air generator include: drying of filter cake sludges; water based paints, water washed components, retrofit gas/heat ovens, and the elimination of humidity in plant environments.
The HYGREX TM closed loop process provides drying at 1/6th the energy cost of conventional drying methods. HYGREX TM units are applied to retrofit existing dry off ovens by simply eliminating the direct gas fired burner box, infrared and steam as the energy source. By using this closed loop process the HYGREX TM dry air generator does not require the installation of exhaust or air makeup, nor does it add heat to the material being dried. This process therefore, eliminates the risk of distortion, as well as cool down zones and tunnels. No odors or gas emissions are generated and the condensed water is reusable.

The drying technology of Hygrex TM can be divided into two product groups:

1) Industrial drying with Hygrex drying technology

Hygrex TM is an innovative low-temperature drying principle for parts and materials of all kinds such as rack materials (car parts, fittings, armatures etc.), bulky material (screws, clasps etc.), continuous drying goods as well as tubes.

• Energy savings of up to 80%
• Drying periods reduced by up to 50%
• Gentle drying due to low temperatures
• High drying quality
• Retrofittings and new drying plants

2) Sludge Drying Systems TLG

TLG sludge dryers too operate on the condensation principle at low temperatures. Until now mainly various types of metal hydroxide sludge, paint and lacquer sludge etc. have been dried in batches of 50 kg/d to 20 t/d. Read more about the principle and applications of sludge drying.
