Best practices usually exceed what is defined in regulatory requirements. Obtaining safety certification is an important step in the product cycle for this reason. It demonstrates a commitment to the safety and quality of the product. Regarding product safety testing, there is a choice in testing partners to conduct the certification review. The following blog entry explores the what and why of safety certification.

A safety standard’s origin story:
Safety standards are developed by such institutions as the American National Standards Institute (ANSI), Underwriters Laboratories (UL), and others. These groups develop and publish their own standards, which gain recognition in one of two ways. A standard might become a government’s regulatory requirement, or a standard might gain popularity from the private sector. As more customers demand a specific standard, more manufacturers and OEMs will seek it for the products they produce.

Compliance versus certification:
In a similar spirit as the phrase “correlation does not equal causality”, note that compliance is not the same as certification. A compliant product might indeed meet a given safety standard, but this a self-reported state. There is no 3rd party oversight to agree or disagree with a manufacturer’s statement of compliance. To gain a certification of a given safety standard, the product must undergo certification testing and this testing must be performed by a Nationally Recognized Testing Laboratory (NRTL). The NRTL is the 3rd party and its function is to test and certify whether a product meets the given standard. The NRTL is disinterested in the outcome of the testing; its commercial reputation relies on the quality and impartiality of its work.

Who is a NRTL?
A Nationally Recognized Testing Laboratory (NRTL) is qualified as such by the Occupational Safety and Health Administration (OSHA). The NRTL Program is part of OSHA’s directive to ensure products are safe for use in the U.S. workplace. It has a say over which private-sector organizations are recognized as capable of determining whether a product meets the safety standard developed by ANSI, etc. In Canada, a similar group called the Standards Council of Canada is tasked with granting accreditation to Testing Organization and Certification Bodies (akin to NRTLs in the U.S.).

Safety certification for TECA products:
Air Conditioners: All versions of our two most popular product families (AHP-1200-Series and AHP-1800-Series) are ETL listed (Intertek) to UL & CSA safety standards. This includes our new certification status for the 24 vdc & 48 vdc input variations of these products. These TECA coolers are ideal for the thermal management of electronics enclosures.

Cold/Hot Plates: The AHP-301CPV, the AHP-1200CPV (includes ERGO-900), the AHP-1200CAS, and the AHP-1800CPV are certified to UL & CSA safety standards. Our cold plate products offer precise, reliable temperature testing on your bench top. Ideal for components testing and laboratory work, these TECA products are versatile. Temperature-control communications software is included. Optional customizations and accessories are available.

The take-away on safety standards:
Regarding product safety testing, there is a choice in NRTL testing partners to conduct the certification review. Choosing an OSHA-qualified or Standards Council of Canada-accredited laboratory to test products will ensure a valid determination for safety certification. Seeking those safety standards which are most in demand will satisfy current customers, help attract new customers, and help make a strong statement about the products’ quality and the manufacturer’s commitment to safety.

Resources:
TECA partners with Intertek to provide our products with the ETL Listed Mark. The ETL Listed Mark is the legal equivalent to the UL and CSA Listed Marks. A product bearing the ETL Listed Mark is determined to have met the minimum requirements of prescribed product safety standards. Intertek is an OSHA-qualified NRTL. Intertek is also accredited by the Standards Council of Canada as an accredited Testing Organization and Certification Body.

Power Efficiency in a Marine Environment

Control Cabinet Cooling:

An engineer, tasked with upgrading a dozen control cabinets on sea-faring vessels, contacted TECA for advice. Although the cooling need was not large, there were many other challenges to the project. TECA’s customer needed a truly robust cooler; something that could be exposed to vibrations, high ambient temperatures of 60degC, and salt spray from the ocean. Furthermore, power efficiency was a must. TECA’s thermoelectric coolers have the highest power efficiency ratings in the industry. TECA Model AHP-590XMHC was able to meet every single requirement.

Control Cabinet Cooling TECA Model AHP-590XMHCLike all TECA “XM” units, the AHP-590XMHC has military-grade fans on both the internal and external sides. Providing protection against salt spray (Mil-Std 810 Corrosion), TECA’s “XM” units also have full protection from exposure to shock and vibration. TECA’s unique ECO-Mode temperature controller feature limits the amount of time the cooler needs to be actively cooling. Utilizing passive cooling in lower demand times draws 95% less current. During high demand times, the active cooling function of the AHP-590XMHC draws 32% less current than its closest competitor on the market.

Cooling RF Device with Liquid Chiller:

under the radar

TECA Corp. manufactures an extensive line of thermoelectric, recirculating liquid chillers. Typically used in laboratories, TECA’s chiller Model RLC-1800 recently adventured out into a more unique application. In this application, TECA was able to help a contractor working for the USAF to reduce cost. The contractor required a replacement chiller with the same form, fit, and function as their original (non-TECA) equipment. The TECA engineering team found a way to modify the RLC-1800 to satisfy the customer’s requirements, while keeping the expense to a minimum. The cooling capacity of the RLC-1800 is our largest in a mountable chiller.

Tight Temperature Control
Food Manufacturing Cold Plate

TECA’s smallest Laboratory Air Cooled Cold/Hot Plate, Model AHP-301CPV, offers precise temperature control, protecting food samples in a sensitive application. In this example, our customer has placed food samples into a simple aluminum block insulated with Styrofoam. The AHP-301CPV Cold/Hot plate can be used to control the temperature to a tenth of a degree. This thermal management solution provides a small footprint. More importantly, the samples can be reliably cooled or heated to a variety of temperatures per the end user’s requirements. Our customer reports the rapid transition between temperatures is beneficial.

 

The AHP-301CPV, part of TECA’s extensive “CPV” product line is a UL/CSA, CE-Marked product with a decade of experience serving in laboratories worldwide. The built-in temperature controller and communications software allow for versatility in use. Modifications and additional accessories are available to suit the end user’s needs. Please explore the different sizes and types of cold/hot plates TECA offers here. If we can be of assistance, please do not hesitate to contact us.

Bill Pay Terminals, Kiosks

Kiosk cooling:

TECA Model AHP-451XE Peltier coolers are protecting over a dozen customized bill-pay kiosks. This example illustrates the power of TECA’s smaller air conditioner models. With just over a 100 Watts of cooling power, the AHP-451XE is meeting the thermal requirements of this fairly large (over 4’ tall) kiosk. Housing heat sensitive equipment including computing core, printer, imager, and a 15” LCD touchscreen, this kiosk is exposed to high ambient temperatures as well.

Payload Testbed

Space Satellite Components

Over a dozen TECA Cold/Hot Plates are operating in a cleanroom environment. As part of a significant research undertaking, the European Space Agency’s (ESA) microwave lab has assembled the navigation payload components of a Galileo satellite on a test bench. Components can be separately temperature controlled, using TECA Cold/Hot Plates. “This is important because part of the facility’s job is to recreate anomalies occurring aboard the satellites, which includes reproducing their environment” says ESA microwave engineer César Miquel España.
