Understanding the Technology

1) Size of the kitchen ventilation system
2) Hours of operation at reduced airflow
3) Climate of your food service facility
4) Available utility rebates
5) Cost of electricity
6) Indirect factors such as improved kitchen comfort and decreased noise

We have tested and have the ability to control dampers. But we do not practice it or recommend doing it because the minimum energy savings to be gained does not outweigh the risk and life safety of the facility.

The first priority for a Type 1 grease duct is to extract grease-laden air from the kitchen hood and maintain the safety of the occupants in the building. Any obstructions in the air flow prevent the duct from performing its core life safety mission. And Melink does not advocate the usage of modulating dampers as a control strategy.

We offer an Energy Saving Report, which provides a comprehensive overview of energy savings with Intelli-Hood installed. Fill out the contact form at the bottom of our Intelli-Hood page to submit your site information. We’re always glad to help.

DCKV will reduce your operating costs. Factors that help determine the total impact include operational hours, cost of energy, heating and cooling loads, and the efficiency of your HVAC equipment.

No, while direct-drive fans are becoming more popular, they are not a requirement for Intelli-Hood.

Yes, Intelli-Hood controls both the exhaust and make-up air unit or supply fan in concert with the exhaust to maintain space pressure. Typically, the system will take direct control of the supply fan. However, there are various options available depending on your building’s application. There are numerous analog and digital I/Os available to interface with the sites BAS/BMS system.

Sure thing. It probably wouldn’t be too “intelligent” if it couldn’t. There are several methods available to talk with your building management system about, including BACnet /IP, digital inputs, digital outputs, scalable 0-10vDC or 0-20mA percent speed references. Our applications engineers are here to help. Please send us an email or give us a call at 513-965-7300. You can also view our Bacnet Protocol Implementation Conformance Statement (PICS) on our resources page.

We can take a 115v or 230v single-phase input through our VFDs and convert it to 208v three-phase. These are special drives, and so we are limited to 1-1/2 hp on the 115v input.

Two options exist for using single phase motors. We evaluate your application and will supply the necessary motors for your site conditions and equipment.

1) Utilize direct signals with single-phase electronically commutated motors to command the speed.
2) Utilize a variable frequency drive (VFD) that is capable of inputting single-phase power and converting to a three-phase power output. For these VFDs to work, the fan motor will typically need to be replaced with a motor capable of receiving three-phase power.

One standard Intelli-Hood system is capable of controlling up to 39 hoods and 64 fans. However, each application is unique and will likely require a tailored solution to meet your operational needs.

Getting Started

By providing us with some basic information, our gurus can provide you an estimated cost range along with an energy savings analysis for your particular operation. We would need the following information:

  1. Number of hoods
  2. Hood configuration (i.e., wall, island, etc.)
  3. Number and size of exhaust collars on each hood
  4. Fan information (hp, voltage and approximate distance from hoods)

Over the years, Melink has designed and implemented three Intelli-Hood systems: IH1, IH2 and IH3. While all work on the same basic principles, they DO NOT have the same parts or interfaces. Watch this video to learn how to identify your system.

Construction Considerations

Intelli-Hood will reduce your overall kitchen operational costs. It will also make the environment quieter through reducing the constant hum of the exhaust fans. Beyond that, the kitchen staff shouldn’t experience any other impact.

No, we’re a controls company. Our focus is on the electrical controls, to make your kitchen hood part of an intelligent and demand-responsive ventilation system. Think of Intelli-Hood as an energy savings appliance. While everything else in your kitchen is adding to the electrical load, this system is actively saving you money in your kitchen operations.

We do partner with many hood original equipment manufacturer companies around the globe to offer direct installation packages for both new and retrofit applications.

It depends on the complexity of the project (how many hoods, configuration, etc.). To offer a benchmark, we can install all the sensors for three hoods in one day. Most retrofit installations take place overnight to prevent interrupting the daily kitchen operations.

Absolutely. We are comfortable with existing kitchen applications and are accustomed to overcoming challenges that come with them. We’ve worked with a huge variety of hood types and system configurations. Our installations cover nearly every market and location – from the top of a mountain to the water line on maritime vessels. No kidding. Our highest installation is at 11,212 feet above sea level. And sometimes the maritime installations go below sea level, depending on how big the waves are.

Whatever the location, your Intelli-Hood system will be installed by our global team of Melink employed or certified installers.

Post-installation Maintenance

There are several connections that go to a Intelli-Hood system. It is important to verify that all the cables are shielded and tight with no corrosion. Watch this how-to video about cable connections.

First, we encourage you to take a look at our resource page and how-to videos. If you need further assistance, please contact us at 877.477.4190 or submit a request to our technical support team.

The Intelli‐Hood optic sensors should be cleaned periodically. In applications with high amounts of grease, they will need more frequent cleaning. To clean, wipe the lens of the optic circuit board with a soft, moist cloth to remove grease.

Temperature sensors rarely need to be cleaned and can be maintenance-free in some applications. To clean, wipe the temperature probe with a moist cloth to remove grease.

Watch this how-to video for an overview of Intelli-Hood maintenance and cleaning.

After Intelli-Hood is installed, we will train your staff on its operation and ongoing maintenance. In reality, there will be virtually no impact to your operations considering the intelligence of the system. For a detailed guide to operation and maintenance, please see our O&M manual on our resources page or view our how-to videos.

If you’re interested in validating your energy savings, we have three tiers of services for monitoring:

1) Remote Connectivity – We can program your Intelli-Hood system to “phone home” to our online Intelli-Hood portal, where you will be given a login to view and download performance reports on an as-needed basis. The system can be connected wirelessly or by a hard-wired Ethernet cord. You will also be notified of any system alerts by an automated email.
2) Premium Monitoring Service – Let us monitor and report on your energy savings for you. We can be the proactive watchdog of your systems’ performance.
3) Preventative Maintenance Agreements – We’ll perform a health check, retrain kitchen staff and perform ongoing maintenance on the system to keep your energy savings at peak performance.

Each optic sensor has a dedicated Air Purge Unit that supplies positive air pressure from the optic enclosure to help reduce any grease or dirt accumulation on the optic lens. The system also performs a daily calibration to adjust the optic sensitivity based on the level of cleanliness. If the optic lens gets too dirty, the system will visually alert the user to clean the optic lens. This video provides an overview about the system’s optic sensors, as well as troubleshooting tips.
