What is a Non-Ventless Dishmachine?
A non-ventless (standard) dishmachine does not include any steam capture or
condensation system. In high-temperature models, steam is produced during
the final rinse and released into the surrounding air when the door opens or when
conveyor wares exit the tunnel. For this reason, these machines require external
ventilation — usually a Type 2 condensate hood — to remove excess humidity,
protect surrounding finishes, and meet sanitation codes.
Non-ventless machines are:
• Simpler in design, often with fewer moving parts
• Ideal for dishrooms already equipped with adequate HVAC and hood systems

Ventilation
Requirement
No hood required
Requires Type 2 condensate hood
Energy Eficiency
High — recaptures energy from
steam
Standard — no heat reuse
Installation Flexibility
High — can be placed in tight
spaces
Lower — must be near ventilation or hood
Cost Savings
Lower utility and HVAC costs
May incur higher installation and venting
costs
Ideal Applications
Small kitchens, bars, cafés,
front-of-house
Large kitchens with existing hood
infrastructure
Initial Cost
Slightly higher
Typically lower base price
Service Complexity
May require specialist servicing
Easier for standard techs to maintain
Comparison: Ventless vs. Non-Ventless
Choosing between ventless and non-ventless warewashing equipment comes down to
more than just preference — it’s about facility infrastructure, throughput requirements,
and code compliance. Ventless units offer flexibility and savings in tight or hoodless
spaces, while non-ventless systems are more suitable for heavy-duty, high-volume
applications in well-ventilated kitchens.
RED Dealers are trained to help you evaluate ventilation requirements in your province,
and can provide hood specifications, energy analysis, and installation advice to ensure
your equipment works in harmony with your space — not against it.
