Caleffi Install at APTN
Designer: Amy From-Playford
Customer: Aboriginal Peoples Television Network
Installation Location: Winnipeg, Manitoba
Brief overview of the project
The 19,000 square foot APTN (Aboriginal Peoples Television Network) building in downtown Winnipeg was remodeled in 2015. One of the remodel goals was to achieve an energy savings of 55% as well as comply with LEED critieria. As part of this project, the original Burnham Cast Iron 1 million BTU boilers were removed and replaced with two APEX 850MBH boilers. The cooling system and all pumps were revamped as well with the addition of (2) 6.5 ton chillers.
As part of the HVAC redesign, a 3” Caleffi Hydro Separator was installed to accommodate the primary/secondary piping required. On the chiller side, a Caleffi 4” DISCALDIRTMAG (NA546M Series) was installed in September, 2017 to remove the ferrous metal particles (magnetite) that were building up in the system. The NA546M has been especially efficient at removing the magnetite.
The design goal was to protect the pumps, filter prior to the VFD to keep dirt from adhering to the impellors and to keep the system clean overall.
This is a new installation onto the building loop for a hybrid system.
Good! The customer is quite happy. All of the occupants of the building have been pleased with the efficient heating and cooling being supplied by the recent improvements..
