Information is provided regarding the company’s CASV system, which the company says represents a radically new concept in mechanical venting of commercial boilers and water heaters. It says its system automatically maintains the boiler manufacturer’s draft requirements by constantly adjusting the flow. It says the concept provides substantial savings over systems utilizing barometric dampers, and offers better draft control, as the draft is 100% controllable. The brochure provides information where some CASV systems are in place.
