Page 2: General Overview
General Overview The Premier DC Series is a multipurpose indirect-fired water heater suitable for many uses. ™ 1. An indirect-fired heater with the top coil extracting heat for radiant or snowmelt systems. Acts as a combination buffer tank/indirect water heater. 2. -
Page 3: Product & Benefits
Product & Benefits The Dual Coil reduces equipment costs and installation time while saving space by combining multiple hydronic system components into one unit. Figure 1 shows how boiler cycling is reduced in radiant heating applications to increase efficiency. Figure 1 Radiant Zone with Domestic Water Controlling Supply Temperature By combining two high capacity heat exchangers in a single unit, the domestic water temperature can provide reliable control of radiant supply temperatures. - Page 4 Product & Benefits (Con’t) Commercial applications require rapid recovery to meet high demands. These sites also have large boilers to accommodate the building(s) heating load. When both coils are utilized to heat domestic water, Premier DC Series ™ have a heat transfer capability far in excess of traditional single-coil and tank-in-tank indirects. The resulting performance can allow competitive bids by using fewer heaters than the competition (Figure 2).
- Page 5 Figure 3 Dual Coil Design Unique exchanger placement and ease of service are two major benefits of the Premier DC Series. Amtrol ™ ® is the only company utilizing a tank design that allows two removable heat exchangers to be arranged at opposite ends of the tank.
