Heat Pipe Vacuum Tube Solar Collector - New Slimline Design

A dry heat pipe collector for ease of installation and maintenance. The dry connection between manifold and tube means tubes can be easily fitted and replaced. A unique temperature limitation device gives added system protection. A choice between two temperature limits provides the perfect hot water solution for your home or business.

Heat pipe technology:

This collector is a 'dry' heat pipe product. In this collector, the heat pipe is attached to the back of the absorber plate. Evaporator fluid is contained within the heat pipe. The energy absorbed by the absorber causes the fluid to change from a fluid state to a vapour state and the vapour rises to the condenser bulb. The condenser is connected directly into the manifold via a dry pocket. Within the manifold the solar system solution is passed across the dry pocket that houses the condenser.

The condenser releases the latent heat of evaporation to the solar system solution and condenses, the condensate returns to the heat pipe and the cycle is repeated.

HP400 collectors are available in 2 sizes:

1. 20 Tube = 2.13m2 aperture area
2. 30 Tube = 3.20m2 aperture area
Up to a maximum of 4 x 30 tubes collectors can be joined together in series with a flow rate of 12 Litres/min.

Unique Feature – Temperature Limitation Devices

HP400 collectors contain a unique temperature limitation device for system protection, there are 2 types:

  • New snap disk to limit temperature to 90°C Ideal for domestic installations.This collector is referred to as HP400
  • Snap disk to limit temperature to 135°C Ideal for commercial installations. This collector is referred to as HP450
