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

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.

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.

WATER QUALITY MONITOR

Water Quality Monitor:

The system pictured below is used to automatically collect and analyze water samples for water quality monitoring purposes. The system can be powered from the grid or from the attached PV system.

The TECA AHP-300 air conditioner is located within the enclosure and is used to keep critical internal components cool during the summer months.

MILITARY COMMUNICATIONS

Military Communications:

A branch of the US military had a need for cooling a small enclosure containing a critical voice communication system. The shipboard system had to be resistant to salt water corrosion as well as pass stringent shock and vibration testing.

Modifications to TECAs AHP-300X solid air conditioner allowed the unit to meet specializing and air flow requirements and pass these tests. The challenge was to overcome the small available space both inside and outside the enclosure. The heat sinks were turned so that the heat rejection air flow and internal cold side air flow moved in different directions.

This unit is a prime example of how flexible Team TECA is when customer needs require customization of standard products.

COMMUNICATIONS COOLING

Long-Term Communications Cooling

A common use for thermoelectric air conditioners is the cooling of electronics cabinets.

These photos show an outdoor communications cabinet being cooled with a system of TECA air conditioners that have been customized for the end user. The units photographed here are over 12 years old, a testament to the reliability of TECA’s thermoelectric air conditioners.

Also worth mentioning is the lack of maintenance that thermoelectric air conditioners require. With no moving parts except for the fans, no filters to change and no chemical coolants, TECA air conditioners are an ideal and environmentally friendly solution for remote areas.

COMMUNICATIONS

A major manufacturer of communications equipment was to go into production of special equipment enclosures, then encountered unforeseen problems with overheating electronics deep inside. The customer wanted air conditioning, but specified that no part of the air conditioner could protrude outside of their enclosure.

TECA designed a little air conditioner inside ducts for hot air exhaust. This way the air conditioner is actually housed entirely inside the enclosure and our customer continues production.

NUCLEAR PLANT

Nuclear Plant:

To cool equipment used for quality control inspection of pipes in nuclear energy plants. Evaluating the condition of pipes in nuclear power plants can be time consuming and costly. Automated and remote guided methods are available. Much of the electronics for the job must be rugged and durable, capable of handling many environmental conditions.

TECA designed, tested and built a system around standard portable cases. The unit shown is the prototype of the production unit, built into the top of a transportation case. Doing the design and prototype work of this nature often leads to happy customers and production jobs for TECA, as it did in this case!
