Hydroflex Ports & Other Products

Hydroflex Systems tanks are provided with two types of penetrations. The first type is referred to as a pipe passage (PP) which is an opening is provided for a given copper pipe size. These passages are constructed of PVC nipples and lock rings. The sizes available are ¾", 1", 1-¼", 1-½" & 2". Pipe passages are intended to be above the water level of the storage tank.

The second type of penetration is referred to as stainless steel connections (CSS). These connections terminate as a male pipe connection in sizes of 1", 1-½", 2" & 2-½". The connections allow for piping to be installed below the water level of the tank and are most commonly used in drain back solar systems.

Water Level Indicator

The CHP water level indicator allows for a quick visual check that the water level is where it needs to be. This is of the utmost importance when you want to ensure your system is operating at its peak potential. Aging water level indicators can be undependable and flat-out incorrect, which is why we offer CHP water level indicators and smart energy system water level indicators that provide accurate and helpful information on demand. When ordered, it arrives installed in the lid and only requires a simple set up after the tank is filled.  It is a very economical solution for necessary regular maintenance.

Heat Exchanger Stand

Heat exchanger stands raise the coil 12 inches off the bottom of the tank. They are used depending on stratification and temperature necessary. Much like water level indicators, aging heat exchanger stands don’t serve your needs as well as they could. We offer our CHP heat exchanger stands and smart energy system heat exchanger stands to ensure you have the parts, tools and resources need to make the most of your water system.
