Our Quick-Connect Kits for the MCR-2D offer a way to quickly arrange your exhaust lines to make it efficient for your installer to connect to termination outdoors. Kits incorporate disconnects that allow you easy access to inspect your exhaust system and disassemble parts for easy and frequent cleaning.  

  • Our kits are designed for current models of MCR coffee roasters. If you have a previous generation model, contact us to get the correct kit. 
  • If you've already taken delivery of your roaster, some field measurements may be required to size your adapters.
  • Made in the USA

Layout A

GeneralLayout requires owner to install two exhaust lines to termination. One 5” (20cm) vent line to accommodate roaster exhaust exiting from chaff collector and one 3” (10cm) exhaust line to accommodate cooling tray exhaust exiting from cooling tray fan.
When to use

- Thru-wall exhaust terminations where exhaust lines diverge (ie. high and low)
- Roasting areas with ceiling heights lower than what other Quick-Connect Kits require

End connection
Owner to connect directly to chaff collector and cooling tray fan. Short disconnect adapters are available for purchase if owner-provided venting does not offer a disconnect adapter. Contact Mill City Roasters.
Layout A benefitLower initial cost
Layout A drawbackMore complicated for installer on site which may result in higher overall installation cost

When to use

- Thru-wall exhaust terminations where exhaust lines run parallel.
- Thru-roof terminations that are not straight up through roof.
- Roasting areas with ceiling heights lower than what other Quick-Connect Kits require.

End connection
Short disconnects on each line to connect to owner-provided venting beyond chaff collector. 
Layout S benefit

- Dedicated lines for roaster exhaust and cooling exhaust reduce potential airflow issues
- Exhaust air can terminate thru-wall
- Short disconnects at each line to allow for cleaning.
- Lower ceiling height requirement

Layout S drawback
Two building envelope penetrations


Layout G
