PREPAC DHW TANK

COMPACT DHW SYSTEMS WITH PLATE HEAT EXCHANGER "PREPAC"

500 to 3000 Litres

CE compliance
2014/68/UE
2014/35/UE

Compact system with integrated plate heat exchanger

"RC" internal coating (WRAS approved material)

Inspection manhole

Stainless steel AISI 316L tank

The PREPAC is a compact monobloc heat exchanger system for domestic hot water comprissing a storage tank and a high-performance heat exchange module (plate heat exchanger, circulator, isolating valves, thermostat, stainless steel piping). .

The semi-instantaneous DHW system provides an economical solution to the problem of hot water with significant variations in flow rates experienced in residential properties.
If necessary, a second thermal device can be fitted onto the tank (dual energy operation).
The PREPAC is available in four different versions of tank to meet all needs:

	Carrbon steel with coating		Stainless steel
Version	RC851	RC951	316 L stainless steel
Capacity	0.3 à 6 m³	0.3 à 6 m³	0.3 à 1 m³
T° max	85°C constant	95°C peak	95°C constant
Special resistance to chlorinated shocks	+	+	++

Advantages

High-performance (high plate exchange coefficient).

Compact (monobloc unit).

Quick and easy to istall (unit supplied pre-assembled).

Easy to maintain (module can be completely dismantled).

Inspection manhole ø 400 mm (depending on the model) :

Easy to maintain.
Thermal equipment can be installed at a later date.

Significant hot water storage capacity to meet peaks in demand.

Less heat generator oparating cycles.

Temperature stability for a distributed DHW.

Water can be stored at a constant temperature of up to 95°C (depending on the model).

Can be combined with any energy recovery or production systems.

Delivered to site with pre-assembled insulation (can be easily removed if required).

Insulated bottom and manhole as standard.

Extended warranty for stainless steel version.

Non-standard versions are available on request.
