Teklab Receives UL Certification for Oil Level Regulators

The Italian manufacturer has also established Teklab USA in Atlanta.

Teklab, an Italian manufacturer of liquid-level regulators, sensors and switches for CO2 (R744) refrigeration systems, said it has received UL certification for its TK3+, TK4 and TK4-Modbus oil level regulators.

In addition, the company has also opened an office in Atlanta, Georgia, as the headquarters of its new subsidiary, Teklab USA.

Daniele Barbieri, who works in Teklab’s sales department, told R744.com that both developments will support the company’s efforts to establish a direct presence in the U.S. and Canada, expand its product and service offering for end users and become the go-to manufacturer for electronic system controls for HVAC&R applications in the region.

Teklab received UL certification for its oil level regulators in September 2023. All three products are designed to monitor the amount of oil in each compressor of a refrigeration system. When necessary, they inject oil captured in the oil separator to ensure proper lubrication and avoid malfunction and inefficiencies.

Offering coverage up to 140bar (2,030psi), Teklab’s regulators are well suited for COsystems.

With over 30 years’ experience working with CO2 and natural refrigerants in the European HVAC&R sector, Teklab has a lot to offer the North American market, he added.

In an interview with R744.com at EuroShop 2023, Teklab’s Technical Director Riccardo Candrini said the TK4-Modbus unit is unique in offering both a wireless and a wired interface and provides more flexibility than other oil level regulators on the market at a lower cost. At the AHR Expo 2024 last week in Chicago, he added that the unit allows operators to “interface [with] their controllers remotely and make adjustments and checks.”

The company is also pursuing UL certification for its optical level sensors, which monitor the level of liquids such as oil in separators or refrigerant in liquid receivers, and alert operators when levels are too low. Teklab expects to receive approval within the first quarter of 2024, explained Barbieri.

In addition, Barbieri said Teklab USA was established in May 2023 to enable the company to provide better service for its customers in North America, where installations of CO2 systems are increasing.

“We understand the important roles that our products play in our customers’ production lines and operations,” he said. “This new division will help us meet their needs with the responsiveness that they require.”

Noted Candrini at the AHR Expo: “We were one of the first companies to believe in CO2.”

Growing demand for NatRefs

Teklab’s decision to establish a presence in the U.S. was driven by its belief that demand for natural refrigerants is set to surge in the coming years.

“North America is experiencing a transition that will dramatically change the HVAC&R market,” said Barbieri. “The market is more than ready for adopting natural refrigerant-based systems. In the next two to four years, we expect to see an exponential growth of natural refrigerants, both for refrigeration and heat pumps systems.”

There are several factors influencing this shift, he explained.

“Market and consumer demand, corporate values and support from clear and timely legislation will be the main elements that will drive the change,” he said. “From California’s laws, incentives and initiatives to recent legislation in Washington, D.C., governmental support for low-GWP solutions is clear. There is also a strong driving force coming from the private sector, which will mark the direction of this path and lead the transition.”

The U.S. market’s transition towards natural refrigerants could result in many opportunities for Teklab, including further development of its products and the opening of a production line in Georgia to meet demand, according to Barbieri.

“In the upcoming months we will share news on breakthrough solutions,” he added.
