We are proud to be the first North American distributor to offer Grandfar's top line of smart ECM circulators comparable to Wilo Maxo and Grundfos Alpha-3 lines in terms of functionality, The GEM PRO line includes all the advanced features you'd expect like fixed multi-speed, constant pressure, variable pressure, auto-adapt modes. They include an internal temerature sensor and will accept an external sensor for delta-T control or heat metering applications. https://thermatlantic.com/gem40-120f-250-pro/

This is the panel mount controller used in all our residential DX2W modules. You will need to specify in your order comments whether you have the first generation 36"x24"x14" coax heat exchanger module or the second generation 24"x24"x14" tube-in-shell heat exchanger module since they have different I/O configurations and software versions. If your system used a tank heater or has floor or panel cooling options or was customized in any way you will need to specify the name of the original customer so we can lookup the software revision used and burn it onto the new controller before shipping it to you. https://thermatlantic.com/dx2w....-panel-mount-control

Purchase this kit if you wish to take advantage of radiant panel cooling with the DX2W-EX3 module controls. The kit comes wih a wall mount dewpoint transmitter and condensate alaem designed to connect to the options terminal strip of the DX2W-EX3 controls. The dewpoint transmitter tells the DX2W-EX3 controller the dewpoint based on indoor relative humidity and ambient temperature so that the controls can modulate the 3 way modulating mixing valve which comes with the DX2W-EX3 to produce chilled water temperatures slightly higher than the dewpoint temperature in order to prevent condensation. https://thermatlantic.com/radi....ant-panel-cooling-ki

We now stock competitively priced PEX-AL Oxygen Barrier (OB) tubing in 1/2" ID in 300 M (985') long rolls to be used with our XPS-AL panels. One roll should be sufficient for four 120 SF bundles of panels. Although PEX-B has become the most popular tubing in North America for radiant heating applications, this is largely due to its lower cost compared to the other two types available. https://thermatlantic.com/pex-....al-tubing-1-2-id-x-3
