MRV – M.A.R.V.E.L. DCKV Demand Controlled Kitchen Ventilation (ETL)

M.A.R.V.E.L., in combination with Capture Jet™ technology, offers the lowest levels of energy consumption currently possible, improves users’ comfort and also provides for future expandability for the operator.

Trusted by the world’s top restaurants, hospitality groups, institutions, and multi-unit operators, M.A.R.V.E.L. delivers unmatched savings in energy, maintenance, and operational costs while improving indoor air quality and sustainability outcomes.

What is Demand Controlled Kitchen Ventilation?

Most commercial kitchens operate their ventilation systems at full capacity, regardless of the amount of cooking taking place. This results in excessive energy consumption, increased HVAC loads, and greater wear and tear.

Demand-Controlled Kitchen Ventilation (DCKV) solves this problem by intelligently adjusting the exhaust and supply airflows in real-time based on the actual cooking activity.
Sensors detect heat, smoke, steam, and particulates, automatically adjusting ventilation as needed throughout the cooking cycle.

This ensures the kitchen exhaust system operates only when necessary, saving energy without compromising air quality or safety.

Frequently Asked Questions

What is M.A.R.V.E.L. Demand Controlled Kitchen Ventilation?

M.A.R.V.E.L. is Halton’s advanced DCKV system that dynamically adjusts exhaust and supply airflow based on real-time cooking activity, using a combination of temperature and optic sensors. It helps reduce energy use, improve kitchen air quality, and lower operating costs.

How much energy can M.A.R.V.E.L. save?

M.A.R.V.E.L. can significantly reduce ventilation-related energy costs by modulating airflow to match actual demand, decreasing fan usage and the need to condition unnecessary air.

How is M.A.R.V.E.L. different from other DCKV systems?

Unlike systems that rely only on temperature sensors, M.A.R.V.E.L. uses automatic balancing dampers and multiple sensing technologies (including thermal imaging sensors and temperature sensors) and provides zone-specific control. It’s also fully factory-integrated with Halton’s hoods and controls for optimal performance and reliability. Halton’s on-board pressure transducers read real-time actual airflows to ensure accurate cfm required.

Can M.A.R.V.E.L. integrate with my Building Management System (BMS)?

Yes. M.A.R.V.E.L. is designed to integrate seamlessly with most BMS platforms, enabling centralized control, monitoring, and data logging.  Both Bacnet MSTP and Bacnet IP options are available.

Is M.A.R.V.E.L. suitable for all types of kitchens?

Yes. M.A.R.V.E.L. is scalable and ideal for a wide range of commercial kitchens — from quick service and chain restaurants to hotels, hospitals, educational facilities, and corporate kitchens.

What kind of maintenance does M.A.R.V.E.L. require?

The system is designed for low-maintenance operation. Sensors and controllers are built for durability in commercial kitchens. Halton also offers maintenance and support services to ensure long-term reliability.

Does M.A.R.V.E.L. affect comfort or performance in the kitchen?

No — it improves it. By adjusting airflow based on actual conditions, M.A.R.V.E.L. enhances temperature control and air quality while maintaining effective smoke and odor capture.

Can M.A.R.V.E.L. be retrofitted into an existing kitchen?

In many cases, yes. Halton can assess your current system and determine if a retrofit is viable. Retrofitting M.A.R.V.E.L. can offer significant ROI through ongoing energy savings.
