Intarcon & Ammolite - HVAC&R

INTARCON was founded in 2007 as a joint initiative of a long experienced work-team in the fields of refrigeration and air conditioning, with the aim to develop a new range of cooling equipment.

Since its creation to develop commercial units of refrigeration, INTARCON (www.intarcon.com) has evolved their offerings towards cooling packaged solutions of medium power.

Their headquarters are located the South of Spain, in Lucena (Cordoba), focusing on international outlook to Europe, North Africa, Middle East and Latin America. To date there are more than 50,000 INTARCON units operating throughout 50 different countries.

As early as 2018, Intarcon was looking for an ammonia compact chiller. After a conversation with them during an exhibition early 2019, they decided to test a miscible oil: Zerol® PAG-R717 52. The purpose was to reduce as much as possible the oil separation circuit, making the unit as compact as possible.

Zerol® PAG-R717 52 is a Polyalkylene Glycol (PAG) designed to be miscible with ammonia. This property enables the engineering team to operate the chiller like a halocarbon refrigerant one. After several tests with the prototype, the oil separator became a simple one of a testimonial size. A detailed calculation of real working viscosity was made in all the operational envelope limits, to ensure the compressor was properly protected against wear and the high/low pressure seal is secure.

The result is a compact chiller with a very low specific refrigerant charge, and a single and simple oil separator that has a greatly reduced and simplified circuit. The greater demand for natural refrigerants systems is now addressed with compact chillers that can be installed without the need of a machine room, and Zerol® PAG-R717 series will help to improve even further the compactness of that equipment.
