If you are installing Thermex, you can be confident you are installing quality.
Manufactured from high specification Duplex 2205
Stainless Steel, our Thermex range is designed
to resist all forms of corrosion, including crevice
and stress corrosion. Its high mechanical strength
promises durability, while automated welding
procedures, post weld pickling and passivating
treatment guarantee each individual weld is as strong
as its parent metal. Our Thermex Stainless Steel Hot
Water Tanks are pressure tested to a full 12 bar - four
times their normal working pressure - and injected
with 50mm of our HCFC free Polyurethane insulation
to achieve astonishingly low levels of heat loss, which
maximises energy efficiency for your customers.
Thermex Stainless Steel Hot Water Tanks provide a
reliable and cost-effective solution to the domestic
hot water heating and storage requirements of
commercial & domestic premises, particularly hotels
and apartments. These tanks are high quality, long
service life stainless steel vessels for projects that
have large volume heating/domestic hot water/solar
HVAC water systems.
Available with twin coils, fully insulated and
Watermark approved, Thermex Stainless Steel Hot
Water Tanks provide quick recovery and are suited to
high demand usage. Key supply advantages include
large stock holdings in a range of sizes, including
compact units designed to fit through standard
doorways.
Thermex range of tanks use high recovery smooth
tube coils for optimal performance. No other coil
type on the market today offers the same transfer
rate as smooth stainless tube.
