RICOR’s New Generation of Linear Cryocoolers Reliability Overview Development Guidelines (2025)
The challenges of designing cooled IR detector systems have continued to grow in recent years, driving the development of more compact, high-resolution systems with improved performance. The demand for longer operational lifetimes, particularly for 24/7 applications and space missions has directly influenced cryocooler requirements.
Extended Linear Cryocooler Development Process Accelerating Time-to-Market and Enhancing Performance (2025)
This article reviews the development and performance of the Extended Linear (ELI) cryocooler models K589 and K591. The focus of this article is the SPRINT development cycle, which emphasizes simulation, risk reduction, and the creation of lean prototypes.
Production overview and R&D Improvement programs status for Ricor’s SWaP-C cryocoolers for HOT detectors (2022)
In line with growing trend of moving to HOT detectors, more than 8,250 Ricor’s SWaP-C Cryocoolers were successfully delivered to our customers for various projects in recent years. During this period, we launched R&D improvement programs to bring more capabilities from the current models.
RICOR’s Advanced Rotary & Linear miniature Cryocoolers for HOT IR detectors (2022)
In recent years, the trend of moving IR detectors to operate from standard 77K to the High Operating Temperature (HOT) of 150K, drives RICOR’s onward development focusing on SWaP-C, a new family of miniature cryocoolers, alongside continuing to make improvements to existing cryocooler models.
From Development and Qualification to Production of Ricor’s Innovative SWaP-C Cryocoolers for HOT Detectors (2020)
The modern needs of the electro optical market for small low-power and light-weight IR systems are impelling development of High Operating Temperature (HOT) IR detectors, requiring dedicated cryocoolers design.
Overview of RICOR’s Reliability Theoretical Analysis, Accelerated Life Demonstration Test Results and Verification by Field Data (2018)
The growing demand for EO applications that work around the clock 24hr/7days a week, such as in border surveillance systems, emphasizes the need for a highly reliable cryocooler having increased operational availability and optimized system’s Integrated Logistic Support (ILS). In order to meet this need, RICOR developed linear and rotary cryocoolers which achieved successfully this goal.
Ricor Cryocoolers for HOT IR Detectors – from Development to Optimization for Industrialized Production (2017)
The modern needs of the electro-optical market for small low-power and light-weight IR systems are impelling research and development of High Operating Temperature (HOT) IR detectors, requiring development of dedicated “HOT” cryocoolers.

Overview of RICOR Tactical Cryogenic Refrigerators for Space Missions (2016)
Cryogenic refrigerators represent a significant enabling technology for Earth and Space science enterprises. Many of the space instruments require cryogenic refrigeration to enable the use of advanced detectors to explore a wide range of phenomena from space.
RICOR Development of the Next Generation Highly Reliable Rotary Cryocooler (2016)
Early rotary cryocoolers were designed for the lifetime of a few thousands operating hours. Ricor K506 model’s life expectancy was only 5,000 hours, then the next generation K508 model was designed to achieve 10,000 operating hours in basic conditions, while the modern K508N was designed for 20,000 operating hours.
