New Slimline Design

Heat Pipe Vacuum Tube Solar CollectorA dry heat pipe collector for ease of installation and maintenance. The dry

connection between manifold and tube means tubes can be easily fitted andreplaced. A unique temperature limitation device gives added system protection. A

choice between two temperature limits provides the perfect hot water solution foryour home or business.

Thermomax Heat Pipe

Technology has evolved...Easy Installation

The unique ‘plug and play’ design of Thermomax solar collectors

makes installation quick and easy. There is no need for heavy lifting

equipment as tubes can be carried onto the roof individually. The

collector is fixed to the roof by easy-fit brackets, which are simply fixed

to the rafter.

Taking it a step further The new slimline manifold is not only lighter than HP200 -

developments to the lid and tubes also make installation easier.

• An improved hinge means the lid is never separated from the

manifold and a tube retaining lip is incorporated into the lid.

• A shorter neck on the tubes, reduces movement, retaining their

flexibility but making them easier to insert.

High Performance Vacuum TubesA superior vacuum is maintained over a longer period of

time through:

• Glass to metal seal – unique fusing process for durability.• Superior vacuum – by creating a vacuum of 10-6 mbar within the tube,

thermal losses caused by conduction and convection are eliminated.

• High quality glass – unique properties give good transmissibility with

low reflection losses and increased durability.

The dry fit of heat pipe tubes allows easy maintenance as tubes can be

removed without draining the system

Performance and Savings

Unique Feature – Temperature Limitation Devices

HP400 collectors contain a unique temperature limitation device for

system protection, there are 2 types:

1. New snap disk to limit temperature to 90˚C

Ideal for domestic installations

This collector is referred to as HP400

2. Snap disk to limit temperature to 135˚C

Ideal for commercial installations

This collector is referred to as HP450

Installation Options

HP400 collectors are available in 2 different sizes –both with the option of the 2 different temperaturelimits.

Designed specifically for higher latitude climates, Thermomaxproducts provide heat even in cold, windy or humidconditions

A superior vacuum in the tube, over a longerperiod of time

Supplies up to 70% of your annual hot waterneeds – reducing dependence on increasingly expensivefossil fuels

Snap Disk Operation

The device is open and

heat transfer occurs

until the condenser

reaches its set

point temperature.

Snap disks operate

and close the device,

stopping heat transfer into

Device re-opens as

temperature falls below the

set point, reactivating heat

LONG LIFE EFFICIENCY• Thermomax solar thermal systems are still working

efficiently after 25 years.

Hermetic Seal• Fusion between the internal copper tube and

the glass ensures lifetime integrity of the seal.

Soda Lime Glass• Soda Lime glass has a much lower permeability

to atmosphere than industry standard Borosilicateglass, guaranteeing the longevity of the vacuum.

SYSTEM SAFETY• Snap Disk offers reduced risk of system overheating

and unrivalled levels of safety .

EFFICIENT HEAT TRANSFER• Ultra-Sonic weld between absorber plate and tube

ensures most efficient heat transfer.

UNIQUE PATENTED

SNAP DISK THERMAL SHUT-OFF

The device is open andheat transfer occursuntil the condenser

reaches 95ºC.

Snap disks operateand close the device,

stopping heat transfer

into condenser.

Device re-opensas temperature

falls below 95ºC,

reactivating heattransfer.

How Thermomax worksThe vacuum inside each tube provides perfect insulationand protects the system from outside influences, such ascold, wet or windy weather and suppresses the heat lossthat is common in the more traditional flat plate systems.

Designed and manufactured for Northern Europeanclimates, Thermomax’s technology also works hardin the winter months. As indicated in the graph

below Thermomax out-performs all typical flat platesolar systems throughout the year in heat output.In the winter months the performance is even moreoutstanding with output being as much as 3 times moreefficient.
