Innovative Condensing Combustion Technology
Hamilton's EVO line is engineered using technology developed and patented in Europe in 1992. To date, this technology has been installed in more than 7 million facilities worldwide. Hamilton has combined the best of this technology with its years of experience in condensing equipment to design and develop a product line that broadens its applications and capacities, and eliminates many of the common mistakes made during installation.
How Condensing Technology Works
In the EVO condensing system, the produts of combustion (some of the wet heat and all of the dry hear) are forced to pass over the portion of the heat exchanger where the coolest water enters the system. At this point, the flue gasses condense, releasing trapped heat that is then absorbed into the water through the heat exchanger. Condensate (water) and low temperature flue gasses are left behind - flue gasses are so cool, in fact, they can be vented through PVC if desired.
EVO Condensing Water Heaters and Boilers
- Efficiency (Up to 99.8% depending on incoming water temperature)
- Construction (All 316L stainless steel is used for the heat exchanger)
- Capacities (Systems from 79,000 - 8,000,000 BTU/hr)
- Common Venting - Up to 8 units may be common vented together - EVO's non-return valves and proprietary software make this possible
- Cascading Controls - Up to 8 units can communicate with each other to operate as one large system, maintaining precise temperature control
- Modulating Burner - Up to 5:1 turndown ratio adjusts to meet demand, further increasing efficiency while reducing cycling
- Pre-assembley Systems - All Rack Packs are factory tested and shipped ready to set in place with minimal assembly, reducing labor costs, downtime and installation issues
- Scale Monitoring - Internal software constantly monitors heat exchanger performance to warn if scale formation is beginning
- Freeze Protection - Controller starts the pump (and the burner if necessary) to protect again heat exchanger freeze-ups in cold climates
- Heating Control Configurations - Outdoor reset, 0-10 VDC, open therm/E-Bus/BMS, remote thermostat, remote sensor, boiler pump, system pump, indirect pump or three way valve - domestic hot water as priority or not. The EVO product line has a multitude of standard control configurations, all of which are possible without adding expensive boards or external control panels
Rack Pack Six Pack Features Include:
- Steel Constructed Rack Mounting - Modular welded steel rack supports the entire system - includes leveling bolts
- Factory engineered Common Venting - Only one inlet air and one exhaust opening required for up to 8 units, AL29-4C stainless steel or PVC (where local jurisdictions allow)
- Common Water Piping - All units are manifolded together with copper and brass plumbing, including individual isolation and drain valves
- Electrical Power Supply (208/240v - 50/60hz - 1ph) - All units and their pumps are pre-wired with breaker panel service disconnects - one field connection
- Common Condensate Neutralizer - All condensate runs from individual units to a common drain system filled with limestone. Design allows for easy refilling when PH begins to drop from neutral (~7.0) at outlet
- Gas Manifold - Welded black pipe gas manifold providing single point connection - includes individual shutoffs
- Cascade Controls - A two wire communication cable between units facilitates the use of this feature, while maintaining independent primary safety controls. In the event of lose communication, control reverts back to the individual units.
