Flat-plate heat exchangers that transfer heat between two hydronic circuits while keeping them hydraulically separate. AHHAC supplies the Hurlcon flat-plate heat exchanger range.
A plate heat exchanger transfers heat between two water circuits without mixing them — essential whenever you need to isolate circuits hydraulically. Common uses: separating a primary boiler/heat-pump circuit from the heating distribution (protecting one from the other's water chemistry), pool heating, solar-thermal transfer, and isolating potable hot water from the heating loop.
AHHAC supplies Hurlcon flat-plate heat exchangers — compact brazed-plate units that pack a large heat-transfer area into a small footprint. The corrugated stainless plates create turbulent flow for highly efficient heat transfer, and the brazed construction needs no gaskets to maintain.
Pool and spa heating — isolates the chlorinated pool water from the boiler/heat-pump circuit so the corrosive pool water never touches your expensive plant. Solar-thermal transfer — moves heat from the glycol collector loop into the storage tank. Circuit separation — protects a sensitive heat source from a large or older distribution system of unknown water quality. AHHAC sizes the exchanger to the required kW transfer and approach temperature.
"AHHAC delivered our 22-zone underfloor system on time, on budget and to spec. The crew were tidy, the documentation was thorough, and the commissioning was textbook."
"We've worked with AHHAC for 17 years. They've installed and serviced our hot water plant across three commercial buildings — and they pick up the phone on weekends."
"Three mobs quoted us; AHHAC's design was the only one based on a proper heat-loss calculation. The system runs beautifully — the others would've been oversized and expensive."
