[INQ. NO. 2609M06] At HARFKO 2026, DIGIPRESSURE will showcase digital pressure control solutions, fan speed controllers for refrigeration and air conditioning, and EEV control solutions.
DIGIPRESSURE’s flagship fan-speed controller series (DPF-LH, new DPF2, and DPF3) is a solution that automatically controls the rotational speed of fan motors to stably maintain condensation pressure in refrigeration and air conditioning systems.
In particular, the DPF3 can be applied to three-phase equipment from 220V to 480V, while the new DPF2 supports 220V single-phase two-channel control, thus allowing for flexible application in various refrigeration and air conditioning environments. Additionally, the company plans to supply integrated controllers combining high- and low-pressure sensors with fan-speed control functions as custom-ordered products tailored to customer specifications.
The new DLS-DLU-AHL EEV controller will also be unveiled at this exhibition. This product is an upgraded model based on the existing DVS series featuring an LCD display, which integrates the control of BLDC- and AC-inverter compressor units and electronic expansion valves (EEVs) into a single controller. It enhances user-convenience by allowing intuitive monitoring of operating status via the LCD screen, while enabling precise control of the refrigeration system and improved energy efficiency.
The new product, in particular, is attracting attention as a next-generation refrigeration and air conditioning control solution that provides energy savings through high-efficiency operation and precise pressure control.
