PUFFERMAS® 2 PDC
HEATING WATER BUFFER TANK FOR HEAT PUMP WITH 2 FIXED HEAT EXCHANGERS AND
MACS® MODULE FOR IMMEDIATE D.H.W. PRODUCTION
APPLICATION
Storage by stratification of heating water, instantaneous production of
domestic hot water (DHW) with high flows and performances and low
temperature on the storage of the primary system.
TECHNICAL DESCRIPTIONS
Puffermas® PDC are specially engineered for heat pump systems. The
immediate and fast production of D.H.W. granted by the outside system
steel plate exchange allow the following benefits:
- to reduce dimensions of the water heater need it
- easy maintenance
- easy maximum hygiene for anti-legionellosis bacteria’s
- to produce more DHW than the quantity obtained by boiler with similar
capacity because heating hot water is stored at an highest temperature
than DHW
MATERIAL
Mild steel outside painted. There is no need of any anti-corrosion
treatment due to the fact that the buffer is in a closed circuit without any
adding air
HEAT EXCHANGER (D.H.W.):
Plate to plate stainless steel exchanger in external MACS® module for
immediate D.H.W. production.
HEAT EXCHANGER (HEATING SYSTEM.):
The thermal exchange is ensured by two fixed heat exchangers in carbon
steel with a top thermal loading system.
INSULATION
(Buffer tank): NOFIRE® 100 mm soft polyester fibre 100% made
of recyclable material, with high Thermal insulation and Thermal
conductivity: 0,039 W/mK. Fire resistance class B-s2d0 according to EN
13501. PVC external lining complete with top cover.
(MACS® module): insulated painted steel carter
WARRANTY
