With the most powerful version FK40/755, we offer customers 15 % more power with the same external dimensions. BOCK® vehicle compressors are equipped with the K valve plate system as standard. They are ideally suited for bus air conditioning with increased cooling power requirements in city-, intercity and articulated buses or in areas with very warm ambient temperatures.
Unique FK valve plate system specially developed for air- conditioning
For air conditioning and normal cooling.
Special K1 housing – Applications for Euro 6
Due to special requirements by customers, there is a demand for additional fastening options on the compressor housing – particularly where there is little installation space available, as is the case in many Euro 6 buses. This has been achieved by means of the K1 special housing, which creates a higher level of stability thanks to the compressor being fastened directly to the vehicle motor.
Special features of the K1 housing:
SEARCH. CLICK. FIND.
The online spare parts catalog allows you to find the right spare parts and accessories for BOCK compressors and units with just a few clicks.
The VAP tool is ideal for finding the appropriate compressors for mobile applications. By inputting the required refrigerating capacity and operating conditions, the tool will display compatible components right away. In the VAP tools you will also find additional details about the suggested compressors.

Danfoss, to meet the needs of G&D Chillers, used the microchannel heat exchanger and DSH inverter scroll with intermediate discharge valve to customize the Optyma™ Slim condensing unit, making it compatible with the high-efficiency refrigerant R-410A.
When the owners of One Tower Bridge—a 15-story office building in West Conshohocken, Pennsylvania—needed to replace its 30-year-old HVAC units supplying the facility’s floor-by-floor VAV system, they turned to United CoolAir’s VariCool EZ-Fit units using Danfoss variable speed scroll compressors due to their flexible modular design and ability to handle capacity, efficiency, and noise challenges.
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.
