  • Application: These system are used for heating & cooling by circulating thermic fluid in metal & glass lined Jacketed / limpet reactors, Glass reactors, Stirred Pressure Autoclave Reactor, Micro reactors, Continuous Flow Reactors, Reaction calorimeters, Rotary evaporators, Heat exchangers, Fermentors etc. in R&D centers, pilot plants & manufacturing facilities of fine & speciality chemicals, bulk drug (API) pharmaceuticals, dyes, intermediates, paints, oils, agrochemical, petrochemicals, oil & gas, chemical research institutes / colleges etc
    • Description: Most chemical processes need precision process temperature control. A heating-cooling circulator is a device that is used to regulate process temperature using thermic fluids or thermic oils. AMAR equipment under the Make in India initiative provides a great import substitute for heating cooling circulators. Being the largest manufacturers of heating cooling systems in India AMAR offers high performance, energy-efficient and powerful systems for a wide temperature range of -90°C to +350°C. These systems incorporate powerful and efficient pumps for thermic fluid circulation. Our systems are suitable for reactor volumes from 100 ml to 3000L. Touch screen models and remote access through PC using SCADA software are also available for ease of operations.
