We provide Amazing Solutions


The concept of storage of critical samples is no more limited to having a simple room with temperature between 2ºC to 8ºC.

Such ineffective solutions lead to excursions in temperature conditions that affect the quality of the stored material over a period in time.

NEWTRONIC Walk-In Cold Rooms ensure the temperature is uniform & within range throughout the room. Customer can also avail the option of 8 probe monitoring with data logging, trending & real-time alarms.

They are supplied at customer-site in a knock-down condition & can pass through standard sized doorways. They are assembled on-site. The installation & commissioning is accompanied with IQ, OQ, PQ protocols & complete documentation.

NEWTRONIC Cold Rooms can be utilized for multiple applications in the Pharmaceutical, Cosmetic, Food & Beverages, Dairy & other industries for all kinds of products intended for storage at low temperatures.
