Eco-friendly excellence: BOCK® semi-hermetic CO₂ compressors
Danfoss BOCK® compressors are the global choice for essential components in commercial and industrial refrigeration, including air conditioning, cooling, heating, heat recovery, and heat pumps. We're committed to a sustainable future by embracing natural refrigerants like CO2 (R744).
Our dedication to environmental responsibility drives the continuous development of efficient and reliable CO2 compressors. This guarantees peak plant efficiency while minimizing investments, energy, and operating costs. Count on maximum operational reliability and runtime, securing your sustainable refrigeration needs.
Features and benefits of HGX CO₂ compressors:
Versatile applications: suitable for a wide range of applications, from cooling in supermarkets and industrial setups to air conditioning systems in transportation
Flexibility: transcritical and subcritical CO2 compressors have a broad capacity range, allowing for adaptable cooling and heating capacities to meet specific needs
High-pressure expertise: special LT* variant designed for subcritical applications with high operating and standstill pressures
Specialized solutions: offers ideal compressors like the HGX12 CO2 T, HGX24 CO2 T, and LT series for smaller performance requirements
Environmental responsibility: supports energy efficiency and environmental standards like the European F-Gas Regulation and the global Kigali Agreement
Comprehensive compliance: meets strict European standards and ASERCOM directives for quality and safety
Transcritical CO₂ compressors - Unmatched efficiency and reliability
Their optimized efficiency leads to the highest EER/COP values in their category, as officially certified by ASERCOM (Association of European Refrigeration Component Manufacturers) for multiple displacement stages. Furthermore, these reciprocating compressors are known for their unrivaled reliability and durability.
Cooling capacity 3-85 kW / Heating capacity 9-182 kW - LP/HP: 100/150 bar.
Subcritical and LT CO₂ compressors - Ideal for low-temperature needs

Located close to various waterways, the University of North Carolina Wilmington (UNCW) takes marine science seriously. Its new MARBIONC Building — a 69,000-square-foot interdisciplinary research facility for marine biotechnology — provides labs for lease to commercial enterprises that require reliable, energy-efficient 24/7/365 cooling. Faced with high humidity and mid-Atlantic climate variations, the building required a chiller plant that could take advantage of a wide range of operating conditions and still run reliably.

Improving indoor air quality by increasing the amount of outdoor air (OA) entering a building is necessary in many facilities. Depending on occupant density, some buildings may require 20 cubic feet per minute (CFM) of outdoor air per person, a volume of air that can increase air-conditioning costs.
