BOSCH BMAC4860DNTF Evaporator Coil

Up to 2,000 CFM: the Bosch coil for large duct systems

The Bosch BMAC4860DNTF is the largest of the Bosch BMAC coils we offer. This cased evaporator coil, 24½ in wide and 30 in high, handles up to 2,000 CFM of airflow in upflow, according to Bosch. Multi-position and compatible with both air conditioning and heat pumps, it is installed by AirGreen in Montreal, Laval, Longueuil, on the North Shore and on the South Shore.

The largest BMAC size we offer

In a central system, the coil sits in the path of the air blown by an electric furnace or air handler. In summer, it cools and dehumidifies that air; in winter, matched with a heat pump, it transfers to it the heat collected outside. In its matching tables, Bosch pairs the BMAC4860DNTF with a single outdoor unit of its BOVA 2.0 heat pump: the BOVA-60HDN1-M20G.

This model is for large houses that move a lot of air through a single duct system, for example an intergenerational home on the North Shore or a large property in Laval heated by a wide electric furnace. It also suits the replacement of a BMAC4860DNTF coil on an existing Bosch system. Bosch does not publish a nominal tonnage for this exact coil: the match with the outdoor unit sets the capacity.

What that much airflow requires

A coil that can handle high airflow is not enough on its own: the cabinet blower and the ductwork have to keep up. Before recommending this model, we check the blower capacity, the size of the main ducts and returns, and the space available for a 30 in high cabinet. Position matters too: Bosch publishes 2,000 CFM in upflow and horizontal left, but 1,850 CFM in downflow and horizontal right.

On construction, Bosch highlights an all-aluminum coil for corrosion resistance and a multi-position drain pan that meets most installations. The coil connects with a 3/8 in liquid line and a 7/8 in vapor line.

Our installation, from estimate to start-up

• Free on-site estimate, then a written quote.
• Confirmation of the match with the outdoor unit and of the availability of the coil, which Bosch has discontinued.
• Setting the coil in the chosen position, sealing the cabinet to the air handler and the ducts, connecting the condensate drain.
• Brazing the lines, vacuum, charging and commissioning, with a check of the TXV that Bosch requires at the indoor coil for its matches.

Sold alone, this coil has no efficiency rating of its own and does not qualify for the LogisVert grant. For a complete replacement, we prepare a quote for the whole system.
