Technical Support

The Danfoss 120B0031 VTZ086AJNR1B is a mid‑capacity piston inverter compressor designed for commercial refrigeration, industrial HVAC, heat‑pump and marine applications. Its inverter drive continuously adjusts motor speed to match the cooling load, delivering 30‑45 % energy savings and low noise operation. Built with a high‑strength steel housing, double‑helix pistons and oil‑free friction technology, it offers long service life and virtually maintenance‑free performance. Compatible with environmentally friendly refrigerants such as R‑410A and R‑134a, it meets the latest low‑emission standards. Installation is straightforward thanks to ISO‑14581 and DIN‑standard connections. Stocked under SKU 999.000.022 and covered by a 2‑year warranty, the VTZ086AJNR1B is the perfect choice for businesses seeking reduced operating costs and high system reliability.

Key Features

Inverter control adjusts motor speed in real time, delivering 30‑45% energy savings.
Variable speed drive (VSD) technology provides low start‑up current and low noise (≤ 68 dB(A)).
Dual‑stage pistons, aluminium cylinder block and oil‑cooled drive ensure >30,000 hours service life.
Integrated Modbus RTU, CANopen and BACnet/IP interfaces enable easy system integration and remote monitoring.
Built‑in protection for over‑pressure, low oil level, high temperature and phase loss.

Use Cases

Supermarket display cases and cold storage facilities requiring high efficiency.
Industrial data‑center HVAC systems for energy‑saving climate control.
Water‑source heat pump installations and heat‑recovery projects.
Marine air‑conditioning and container refrigeration where space is limited.
