HEAT TRANSFER PRODUCT RELEASE: For more information, contact: John O'Reilly LNC Communications LLC 815.469.9100, ext. 302; John@LNCmail.com Heat Transfer Unveils High-Efficiency ModCon Boiler To Handle Commercial Heating Loads, Big and Small Modular, modulating and condensing, 94%-efficient unit features 5-to-1 turndown ratio, double stacking, and a compact footprint. EAST FREETOWN, MASSACHUSETTS (JANUARY 28, 2008) - The new, 94%-efficient ModCon Commercial Condensing Boiler from Heat Transfer Products features a high-grade Inconel, load-matching gas burner with a five-to-one turndown ratio, to meet the variable needs for space heating and domestic hot water in a single application. The 500,000 Btu per hour model, for example, will operate as low as 100,000 Btu/h, saving energy on warmer spring and fall days when the heating load is light and spans just a few hours. In addition, direct-vent sealed-combustion ModCon boilers can be stacked, two at a time, to double capacity while maintaining the same small footprint. For use in hotels and office buildings - both in new construction and for renovation or replacement projects - up to eight ModCon units can be combined to handle large heating loads. The new unit is especially suited for multifamily residential buildings that must avoid system shutdowns to maintain heat for tenants. "The Heat Transfer philosophy is dedicated to both ModCon [modulating condensing] technology and modular boiler setups," explains CEO Dave Davis. "Instead of a single massive boiler firing to the max 24/7/365, regardless of demand, our modular concept connects multiple, modulating, high-efficiency boilers that save substantial amounts of energy by matching their inputs with the fluctuations in heat load. But these same smaller boilers, when joined together, can also meet the large-volume demands of bigger buildings." In addition, boiler controls are set up to permit built-in redundancy, notes Davis, so that the system is always supplying heat to the building. If repairs are needed, instead of shutting down the entire system and depriving the building of heat, the technician need only remove the boiler requiring service or replacement. "It's not uncommon for apartment leases to waive an entire month's rent if the building goes without heat for one day," he comments. "These apartment owners cannot afford to cut off the heat for any appreciable length of time." Using a Dungs gas valve that has been tested to UL, FM and CSA standards, the low-NOx burner on the ModCon boiler offers reliable spark ignition and whisper-quiet operation. Fuel conversion from natural gas to liquid propane or vice versa can be done in the field. Other key features on the new ModCon Condensing Boiler include: - Gasket-less heat exchanger, constructed of 316L stainless steel, includes a 150-psi (pounds per square inch), factory-installed relief valve. The heat exchanger uses a large, high-quality surface area to extract all the latent energy from the combustion process, as well as from the by-products of that process, resulting in a thermal efficiency of 94%. "Like our other condensing boilers, the ModCon extracts so much heat that the resulting low exhaust temperatures permit venting with Schedule 40 PVC or CPVC pipe as well as stainless steel," says Davis. Vent runs (horizontal and vertical combined) are permitted up to 200 feet. - Outdoor sensing with indirect priority allows for greater energy savings and comfort. - Patent-pending system for collecting condensate produced by the combustion process includes overflow protection. A condensation neutralization kit is optional. - Built-in electronic staging allows the controls on one unit to manage up to seven other, connected boilers to handle high-volume applications. - LED status indicators (supply and return temperatures, water level, electrical current, etc.) allow easy real-time monitoring of the system. - Remote monitoring and control through a personal computer can be through a USB connection on the boiler. Monitoring software is also available as an option. - Integral low water cutoff with an additional high-limit manual reset is standard on all models. The new ModCon is relatively light and easy to handle. Casters are optional for easier movement of the units, all of which have adjustable legs for positioning on uneven floor surfaces. Three models are available with maximum inputs of 300,000, 500,000 and 850,000 Btu/h. Other options include a high and low gas pressure switch, flow switch, alarm bell and vent kit.
