Cooling Variable Frequency Drives

Steel Mill Enclosure Cooling:

A major steel company has multiple equipment enclosures, housing 4 variable frequency drives (VFD) each, to control their industrial cranes. The high temperature in the steel mill was causing excessive shutdowns. Compressor-based air conditioners could not survive the electrical enclosures’ harsh ambient environment on the overhead cranes. The only input power available was a widely varying 250 VDC, which complicated things. TECA successfully and affordably customized a flush-mounted (external to enclosure) thermoelectric air conditioner to meet the customer’s needs.

Specializing primarily in the food and beverage processing industries, one of our longtime customers uses TECA air conditioners in several applications. These include cooling or heating LCD screens, desktop computers, thin clients, and KVM kiosks. The locations of these applications are indoors, outdoors, in cold rooms and baking areas.

TECA’s comprehensive line of air conditioners fit the bills. We offer each model in different configurations according to the customer’s need regarding input voltage, mounting and application environment.

COAL ANALYSIS

Coal Analysis:

A customer required a constant temperature to keep his detectors working in a coal analysis application. Due to experiencing failures with a competitor’s air conditioner, the customer reached out to TECA.

The solution was TECA’s FHP-1501XEHC Model, a versatile thermoelectric air conditioner offering heating and cooling as well as dual voltage: 120 or 240 VAC input. Built with an industrial grade sealed fan and components, the FHP-1501XEHC is suitable for NEMA-4 enclosures.

AERONAUTICS

A leading military and aeronautics contractor needed a cooling solution for an enclosure which would be on a high altitude vessel. The system would be exposed to high winds and ambient elements present in the altitude.

Working with the customer; TECA sales and engineering team designed a cooling solution with specific intake and exhaust characteristics along with custom paint and finish process that could withstand the conditions it will be exposed to.

ANALYZER COOLING, HARSH ENVIRONMENT

Analyzer Cooling, Harsh Environment:

TECA’s Model AHP-1202XEHC Thermoelectric Air Conditioner provides accurate heating and cooling for the customer’s analysis machine. The environment is harsh: it is in a cement plant.

The customer’s product quickly analyzes composition of raw materials, allowing for increased productivity. TECA’s AHP-1202XEHC provides reliable thermal management within a harsh environment. The AHP-1202XEHC has an industrial grade sealed fan and sealed hot side components, allowing for frequent wash down (NEMA-4).

The solid-state construction is the perfect low-maintenance solution for hard-to-access areas. There are no filters to change and no moving parts except for the fans.

TECA air conditioners use robust thermoelectric modules and boast a long service life.

PORTABLE SECURITY EQUIPMENT

Portable Security Equipment:

Site monitor and security equipment for oil fields and transfer stations needed more security. A portable enclosure housing cameras, WI-FI access, antennas and a Mac Mini computer inside leveraging the Mac platform to provide virtually instant access, hi speed, via “Wild Blue”. The system will be like a watchdog that they can strap on wherever they need the monitoring.

With a slight modification an AHP-1200XE thermoelectric cooler provided the best solution while keeping the NEMA-4 rating of the enclosure.

FOOD PROCESSING

Food Processing:

A European manufacturer of special equipment for processing fruits and vegetables needed to cool sensitive electronics on their line of produce-processing machines, which sort products by color, size and weight.

TECA Model AHP1200XE solid state air conditioners were selected.

The equipment in use is washed down frequently, so the Model AHP1200XE is ideal because it is designed to meet NEMA 4 and suitable for wash-down environments, while it also carries the CE Mark.

RUGGEDIZED MILITARY APPLICATION

Ruggedized Military Application:

Sometimes it just takes a long time to get to the heart of a problem. AHP-1200X “quick quote” for two thermoelectric air conditioners came into our sales team. It was responded to and followed up. The application was reviewed, a quote was made and an order placed.

Only after did we learn that the hard requirements they were looking for were:

  1. Dual adjustable temperature control (heat and cool)
  2.  28 VDC operation and
  3. Military environment.

Fortunately the selections within TECA’s enclosure air conditioner family are large. The military Contractor borrowed a unit from TECA’s loaner stock and based on that success, placed an order. It was then that we found a problem.

It seems that the application was to cool some sensitive electronics out on a 200 meter DC input which caused droop in the input which in turn caused a ringing in the circuits. The new digital monitors being used were susceptible while the older tube monitors had no issue.

Working with the customer it was determined that by changing the controller to a ruggedized PWM controller all problems were solved.

Fire Safety Switches & Alarm Enclosure

Fire Safety Switches & Alarm Enclosure

TECA provides standard off the shelf as well as custom designs to meet the needs of the end user. Alarm enclosures can be exposed to some of the harshest conditions like the extremes of live-fire heat and hose-down. The alarm enclosure pictured here is for fire safety and switches. The transparent plastic enclosure is accessible and secure while being cooled to desired temperatures under harsh firefighting conditions. In this example TECA provided custom modifications to provide for redundancy and mounting requirements specified by the end user.

Contact teca@thermoelectric.com to inquire about custom designs for your needs. Our friendly sales team looks forward to hearing from you!

 

OUTDOORS KIOSK

Outdoors Kiosk:

An original equipment manufacturer designed a new outdoor information kiosk and required a small cooling solution, before they could start up manufacturing.

We consulted with the customer’s engineers and recommended TECA Model AHP-300XE, to provide the necessary cooling in a compact size. The AHP-300XE is an ideal choice for the application because it is a NEMA4 solid state air conditioner, designed for outdoor use.
