Commercial Set-up

All our commercial SUN EQUINOX systems use the same system design, but are sized appropriately for each demand.

Tank

An unpressurized, atmospheric tank made of impact resistant plastic. Double shell construction filled with excellent foam insulation.

The tank is filled once with unpressurized tap water without additives. This water is not consumed it is only used as a heat transfer.

The design has optimum water hygiene since the domestic water is entirely contained within the stainless-steel heat exchangers that are heated from the storage tank water. The heat-exchangers are made of corrugated stainless-steel which provides a self-cleaning design to prevent the chance of legionella and other water born illnesses.

The commercial system set-up is a flexible design that allows us to size a system for any demand, this is possible since the tanks can be manifolded together and work as one unit, providing almost limitless capacity.

Adding Solar

Incorporating solar to the SUN EQUINOX HEATING SYSTEM is a matter of adding a pump, the solar field, and a few simple connections then the SUN EQUINOX is solar ready.

The SUN EQUINOX is a glycol-free, drain back system that uses Apricus evacuated tube collectors or SolarHot flat plate collectors.

Heaters

The Noritz is Energy Star qualified and has a double heat exchanger made of stainless-steel and copper that reduces carbon dioxide and improves efficiency up to 93%.

Pumps

Our easy and flexible design allows us to use a one-size-fits-all pump for every application. This is a tried and true method that makes designing the system easier with less chance for failure.

Controller

This allows us to control and monitor:
Pump— on and off
Temperature— top and bottom of tank
Top out Temperature
Frost
Bio safe

We send the controller pre-programmed, but all settings are installer adjustable.
