Gobi Solar Collector for Active Water Heaters - Open or Closed Loop Systems

Solar Collectors-or panels-gather energy radiated by the sun and convert it into useful heat in the form of hot water. Collectors work alongside your conventional water heater to ensure year round hot water.

Named after the harshest desert of the world, the Gobi collector features an attractive and permanent frame that is designed for good looks as well as weather resistance in both very hot and cold regions. Because of its special absorber coating, the Gobi operates efficiently also in the winter for year round hot water production. Its output will not reduce with age as is so often the case with other solar collectors.
GOBI also stands for: Great Output Best Investment.

Redesigned in 2011!

The new GOBI has undergone a complete transformation for 2011 making it the industry’s best flat plate collector. By redesigning the frame and incorporating state of the art components, the GOBI has a reduced profile and even better performance. With 3 sizes and 2 absorber surface types to choose from, there is a GOBI collector for every type of solar water heating application

Thinnest Profile – The redesigned frame is easier to handle for installers and offers the end user a streamlined, sleek look on their roof compared to bulky traditional flat plate collectors.

Rated Top Performance – New SRCC ratings certify that the GOBI now ranks among the best OG-100 collectors. The high energy output of the GOBI offers maximum performance out of the solar hot water system.

Easiest to Install – The GOBI retains its unique Dyn-O-Seal (DOS) union interconnection method. DOS unions come factory assembled and eliminate the time consuming task of soldering each collector together in an array.

Product Applications

The Gobi is designed for the heating of:

  • Domestic and commercial hot water
  • Homes, Offices, Warehouses
  • Pools, residential and commercial
  • Industrial process water
  • Waste water
  • Cooling with absorption chillers

New Design Features

• 1" reduction in frame thickness
• Improved insulation
• Full plate absorber
• Rounded frame edge
• OG-100 certified with higher performance and efficiency


GOBI Features

  1. Low profile, 6063-T6 anodized aluminum frame makes the collector extremely rigid and rust proof
  2. Factory fitted 1” Dyn-O-Seal inter-connections eliminate the need for soldering when connecting or capping off collectors
  3. Pipes sized for minimal pressure drop and optimal flow
  4. Double-strength tempered low iron solar glass with anti-glare finish resists potential damage from harsh weather conditions
  5. 2.8” thick profile makes the GOBI the thinnest collector available in the U.S.
  6. Weep slots minimize condensation
  7. Built-in flange for mounting without collector penetration

  • Collector wind load certification to 50 lbs. / ft
  • Rack wind load certification to 60 lbs. / ft

How It Works

This liquid flat plate collector is designed to absorb solar radiation. The solar radiation is converted into heat on the inner all-copper absorber. The copper tubes attached to the absorber contain a liquid, either water or a water antifreeze mix, which transports the heat to storage, either a solar tank or a water heater. This process continues until the tank is hot for evening and morning use whenever enough sun is available.

Extra components are required for a complete system to transport the heat to storage and assure its freeze protection.

The Gobi collector features an attractive and permanent frame that is designed for good looks as well as weather resistance in both very hot and cold regions. Because of its special absorber coating, the Gobi operates efficiently also in the winter for year round hot water production. Heliodyne offers the easiest mounting hardware, modular kits for sloped roofs and tilt-up racks for flat roofs or ground installations.
