Demand Control Kitchen Ventilation
CaterSense Demand
CaterSense demand reduces energy consumption at times of low cooking load. The energy consumed by supply and extract fans, plus supply air heater batteries when fitted, makes up a significant amount of a buildings energy consumption.

Our Philosophy
  • Keep it simple
  • Low maintenance
  • Low capital cost
  • Fast return on investment
  • No contractual tie-ins
A commercial kitchen is a potentially hazardous environment, so its not just as simple as turning the fan speed down and hoping for the best. Products of combustion, increased fire risk and even cooking fumes and particulate all increase dangers in the kitchen environment.

Trent are unique in the industry as gas equipment manufacturers, control system integrators and members of Gas Safe. This provides confidence that our systems not only save energy, but also maintain the safety and effectiveness of the ventilation system.
CaterSense Demand System
Achievable energy savings, differ for every project. However savings are always significant and worth pursuing. A typical R.O.I. can be as low as 12 months!
The most resilient demand control system for commercial kitchens
CaterSense demand is a turn-key package, starting with a survey and case study where we develop the right system for your kitchen. Once you are happy to progress, the installation is carried out by our approved team of installers and the system is re-commissioned with a reduced minimum set point. For gas kitchens, a new CP42 certificate is issued along with all of the relevant checks and monitoring to ensure your new energy efficient kitchen is safe. 
Unlock an energy saving of up to 80%
Other benefits of installing a CaterSense demand system include reduced noise levels at times of low service and a reduction in draughts. This creates a better experience for diners and offers further energy savings associated with restaurant heating and cooling where applicable.

Cube Law
Halve energy use, with just a 20% reduction in ventilation speed.
Using the principle of cube law, just a 20% average drop in ventilation speed can halve energy use.

This is because the energy consumed by a fan motor is not in direct proportion to the fan speed. Instead it follows Cube Law, therefore making significant savings possible with even the smallest of reductions.
Commercial kitchen energy saving, return on investment, best ROI
By monitoring duct and room temperature along with CO2 levels, CaterSense can accurately and reliably provide reduced ventilation at times of reduced cooking load. This offers considerable savings and a fast return on investment.

CaterSense demand uses temperature & atmospheric sensors in combination with additional user control, to maintain supply and extract ventilation rates in accordance with the cooking load. 

CaterSense will always operate at the most effective speed required by the cooking load, defaulting to background ventilation at times of low use. When cooking processes that create high levels of smoke or steam are underway, the sensors will detect this. 

When starting cooking processes which create excess amounts of smoke or steam, the useful boost feature is used to pre-empt a possible canopy spill. Following the temporary boost, ventilation speeds revert to sensor control.

Standard Equipment

  • Duct mounted temperature probes

  • Wall mounted temperature sensor

  • Carbon dioxide sensor

  • Carbon monoxide sensor

  • Multi-function controller

  • Ventilation boost

A Resilient Alternative 

Our system has been designed for the majority of commercial kitchens and uses a combination of tried and tested temperature and atmospheric sensors. You will notice there are no troublesome optical sensors on our standard system as they are prone to failure and require continual maintenance. 

Our speed boost feature is
a hit with kitchen staff!

Our simple and effective boost facility is the sure way to increase ventilation, moments before it is required instead of waiting for a sensor to pick up on a canopy smoke or steam spill. Following the boost period, the ventilation reverts back to temperature and atmospheric demand control.

We've also left out gas metering to reduce cost, minimise unnecessary components and improve reliability. For DCKV systems, gas metering doesn't always directly correlate with the ventilation requirement and therefore should only be used if it is of the correct type, accurate and to suit the specific cooking process.

Considerate Design

  • Space heating & cooling

  • Grease separation

  • Fire strategy

  • Gas safety

  • Ventilation equipment lifespan 

Your existing kitchen ventilation system will have been designed to operate at either a fixed speed or within a pre-set band. This should have been determined by a number of factors such as minimum extract rate for gas safety and minimum velocity for grease separation. 

In cases of gas supplied kitchens, during the times when you have little to no cooking load, your ventilation will be running at the speed required for all gas appliances turned up to full. It's not as simple as proportionally reducing the speed to minimum based on the amount of cooking taking place. There are other factors to consider such as space heating and cooling , grease separation, potential hazards from hydrocarbons, particulate matter and the risk of a faulty appliance producing carbon monoxide. 

Equipment, controls & safety are fully integrated to perfectly match your ventilation needs

The CaterSense demand algorithm, balances multiple sensors to ensure the highest levels of safety at all times. Fast reaction times also means that efficiency is maximised while maintaining safety.   


Site Survey

An initial site survey is carried out to gather useful information regarding cooking times and processes, equipment details and installation requirements. Data-loggers are installed to record temperatures, flow rates and atmospheric conditions of the existing kitchen. This data will provide the basis for a bespoke project design and help to produce a R.O.I forecast for your consideration.


Our demand systems are supplied and installed by us to ensure peace of mind and best value for money.

Our expert installation team is fully trained to possess the relevant competencies and qualifications required. Trent are members of the Alcumus Safe Contractor scheme and Gas Safe register. 

Full Turn-Key


Commissioning is included as part of our full turn-key package. This also covers the provision of a CP42 gas safety certificate, where gas appliances are present.

Expert commissioning also ensures you get the most from your systems and includes client demonstration.

Service & Maintenance

There is no tie-in with annual maintenance contracts or costly subscriptions. Once we have installed your CaterSense demand system you are free to make your own arrangements.

However, optional maintenance is available and qualifies for our extended lifetime warranty (25 years)
