Air Changes
A standard system utilizes 10,000 CFM of air movement through an 18" diameter duct, which is completely variable up to this maximum. When required, personal utility blowers provide suction at each work station, generating variable air flow. Both general ventilation and specific job ventilation can be achieved at the same time.
Reports on the number of air changes, temperature and air velocity are provided on daily basis. Solutions for confinement and containment can be designed for larger spaces.


Heat
A flameless source of dry heat with variable outlet temperatures up to 171°F (77°C) can be provided. Very quiet, diesel-powered units burn 4.9 gallons (22 litres) of fuel per hour at maximum output of 600k BTU at 6,500 CFM. This technology does not create any exhaust products in the confined space and does not deplete available oxygen. With adequate external containment an internal temperature of 70°F (22°C) can be maintained with external temperatures as low as -40°F or C.


Humidity
Low humidity to support coating and blasting activities is achieved through the a new technology to generate dry heat. In contrast to the conventional Hermann Nelson type heater, which creates exhaust in the confined space and utilizes available oxygen, these are external units that use a friction plate inside an oil cooler container to generate heat which is blown in from a radiator.


Explosion Proof
Systems and auxiliary equipment can be explosion proof upon request. They are bonded and grounded throughout to eliminate any electrical hazards or static build-up.


All these capabilities allow for parallel path maintenance activities. Contractors are able to put more men inside simultaneously and complete the work in a shorter time frame, saving the client significant down time, while workers are more productive and happier.
