DHW STORAGE TANKS

300 to 10 000 Litres

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

"RC" internal coating (WRAS appoved material)

Stainless steel AISI 316L tank

Renforced thermal insulation

Solar and classic DHW version

The DHW storage cylinder is designed for use with energy recovery systems to amass a water
reserve to cope with peaks in demands. If necessary, a backup system can be used to provide additional
energy.

This device has been specifically designed to meet the production and storage needs of solar domestic hot water (collection and backup) in the service and manufacturing sectors.
There are three different types of tank available to meet all needs :

Carbon steel

Type of coating	RC851	RC951
Capacity	0.3 à 10 m³	0.3 à 10 m³
T° max	85°C	95°C
Duration T° max	Constant	Peak

Stainless steel

Nature of the stainless steel	316 L stainless steel
Capacity	0.3 à 10 m³
T° max	95°C constant
Special resistance to chlorinated shocks	++

Avantages

• Inspection manhole ø 400 mm*:
– Easy maintenance
– Thermal equipment can be installed at a
later date.
• Significant hot water storage capacity meaning that peaks in demand are met.
• Particularly suited for use with solar energy recovery systems (dimensions of
nozzles, number and location).
• Can be combined with any energy recovery or production system.
• Delivered to site with pre-installed insulation (for carbon and stainless steel cylinders only) and thermal backup system (can be rapidly removed if required).
• Insulation of the bottom dished end and the manhole as standard.
• Storage of water at a constant temperature of up to 95°C (depending on the model).
• Extended warranty for stainless steel version.
• Non-standard versions are available on request (higher pressure and special dimensions).
