Horizontal type inner
tank body made of non-magnetic, mirror-finish,
TIG-welded SS 304-grade stainless steel,
with working pressure of 2.5 kg/cm2 for protection from corrosion and wear |
| |
4-mm thick low-iron,
non-magnetic, toughened glass, with
iron-oxide content of 0.01% and solar
transmittance >91% to increase solar
gain and reduce direct solar reflection
& glazing heat loss in FPC products |
| |
High-density eco-friendly
PUF insulation for storage tank to facilitate
heat retention up to 48 hours |
| |
High-density (100-mm)
and resin bonded rock-wool insulation
slabs (at 48 kg/cm2) in flat plate
model collectors & tanks for
heat retention through cold nights (25oC
outside temperature) |
| |
In-tank auxiliary
electrical booster with adjustable thermostat
to quickly deliver 25 litres of extra
hot water in cloudy/cold weather conditions
or emergencies. The standby geyser automatically
shuts down when it hits the pre-programmed
thermostat level of 60o to 80oC? |
| |
Iridium-activated
sacrificial anode to effectively tackle
the corrosive potential in hard water
and frost, and prevent damage to solar
storage tank, water heater and other
connected parts – a simple, replaceable
component that can prevent expensive
replacement of the complete storage
tank in case of high corrosion (Unique
feature) |
| |
Exclusive serrated
copper fins (9), deep-embossed by ultrasonic
bonding for greater solar absorbency
(Unique feature) |
| |
All welding joints
in collectors and tanks pressure-tested
at 5 kg/cm2 and leak-proofed |
| |
Fins, headers, risers
and internal pipes made of electrolytic
(99% pure) copper for high thermal conductivity |
| |
Selective area plating
with NAL-patented NALSUN black nickel
chrome (with > 96% absorbency &
<14% emissivity) for super-efficient
absorption of solar heat |
| |
Anti-corrosive powder-coating
for outer surface of tank & collector |
| |
EPDM beading and gaskets
for perfect water/rain proofing |
| |
Steam hose pipes connecting
collector and tank with GF-coated fittings
(composite pipes with brass fittings)
for long system life |
