Exhaust ducting & general information
1. Throughout the remainder of this document, the term exhaust ducting refers to
the ducting that the customer, or their contractor/representative, select, acquire, and
install. The exhaust ducting will connect to the applicable Primo Roasting provided
equipment.
2. One of the most important aspects of the equipment installation is the use of an
approved exhaust ducting system. Its design can greatly affect the equipment
performance and the product quality. The cost and time to order and install the
exhaust ducting are also important customer considerations.
3. Designing the exhaust ducting system requires a qualified professional to calculate
the efficiency of the system and the proper size of ducting. The ducting must be of
sufficient diameter to accommodate the air flow (SCFM - standard cubic feet per
minute or SCMH - standard cubic meters per hour), and meet applicable regulations. A
licensed engineer or Heating, Ventilation, Air Conditioning (HVAC) professional can
assist. Information the qualified professional will need, such as the diameter of the
exhaust ducting and the maximum exhaust air flow, is located on page 3 Technical
Data table. Customers should contact their sales or project manager representative
with any questions.
4. A properly designed and installed chimney and rain cap is essential to the
equipment performance and longevity. Water leaking in may cause an electrical short
or damage the equipment. Your contractor will be able to coordinate with local
jurisdictions for the correct cap. The cap should not have a screen since it will clog
with residue of chaff over time.
5. The Primo Roasting Equipment (roaster, cyclone, Afterburner, loader, or destoner,
as applicable) MUST NOT support the weight of the exhaust system.
6. The exhaust air from Primo products fits into one of the two general categories.
Either hot exhaust air, such as from the roaster or an afterburner; or ambient/room
temperature exhaust air, from products such as loaders and destoners. The sections
that follow will discuss ducting considerations specific to these general categories.
