Types of Pharmaceutical Chillers

Pharmaceutical chillers are important parts of the drug-manufacturing industry. Nearly all medicines require chilled water in their manufacturing, from antibiotics to complex cardiology medications. Chillers provide precise control over the water-chilling process, and pharmaceutical chilling plants have 15 to 1000 tons in terms of cooling power.

Pharmaceutical chillers come as central process chillers and compact process chillers. Central process chillers can handle 10 to 200 tons, and compact process chillers work well for 1 to 40 tons. Compact process chillers are smaller, which makes them ideal for small spaces. All pharmaceutical chillers feature components that include evaporators, pumps, refrigerant relief valves, cooling towers and pipes, condensers, compressors, filters, fans, and tanks. They come with either an air or water condenser.

Four Main Types of Pharmaceutical Chillers


These chillers come with a water or air condenser, reciprocating compressor-motor assembly, an expansion device, control panel and wiring, a compressor motor-starter, interconnecting refrigerant piping, auxiliaries, and oil and refrigerant charge. They’re a common type of chiller, and manufacturers have improved them quite a bit over the years. When it comes to size, you can find many models that fit through a 30-inch door.

Reciprocating chillers have many advantages. Manufacturers offer them in capacities of up to 200 tons. They’re easy to use with modern designs and controls, and since they’re common, users can find technical support for them without much hassle. They can use environmentally acceptable refrigerants, and many reliable manufacturers sell them.

Screw-Driven Chillers

Screw-driven chillers with screw compressors usually have capacities of under 300 tons. They’re called positive displacement devices because they compress refrigerant by reducing the refrigerant chamber’s size. The screw compressor squeezes two rotating helical rotors that compress the refrigerant. These chillers come in sizes of up to 40 percent smaller than centrifugal chillers, which is one of their advantages. They also have a quiet operation due to the fact that they have rotary motion and not many moving parts.


Like reciprocating chillers, centrifugal chillers are very common with more than 80,000 in operation in North America. Their evaporator functions as a heat exchanger to remove heat from chilled water. The heat then boils refrigerant to change it into gas form. The compressor assembly consists of a centrifugal compressor and a prime mover. Centrifugal compressors are non-positive displacement type compressors, which change kinetic energy into pressure to raise the refrigerant’s temperature. The condenser also acts as a heat exchanger to take heat away from the refrigerant, which changes the refrigerant into a liquid. Heat gets redirected to condenser water and then to a cooling tower. Once turned into liquid form, refrigerant passes through an expansion device.


A heat source provides absorption chillers with the energy to cool water. These chillers use water as the refrigerant and lithium bromide as the absorbent. The absorption process is thermochemical rather than mechanical, and it occurs inside a vacuum, which allows water to boil at a lower temperature. The heat source is a direct heat source from natural gas or an indirect heat source from waste heat, steam, or hot water. Double-effect absorption chillers recycle some of the waste heat produced, which makes them more efficient than single-effect absorption chillers. These chillers can handle a volume ranging from 4.5 tons to several hundred tons of cooling.

General Manager

Sam graduated from Dunwoody College with a degree in HVAC Service, and started out working in the resident side of work. After many years in the residential side of work, Sam took a chance back in 2018 to work in the commercial side of hvac with Jc younger. Since started working with them, Sam has been streamlining Jc younger to make the service side quicker at getting customer back to cooling right away. He always puts the customer needs first, giving them great customer service, and getting them back cooling right away. When Sam is not at work he enjoys hitting up breweries around the area, going up to the cabin, and doing remodeling projects. He also enjoys going out to lake of the woods for some good walleye fishing.In his free time he enjoys taking his grandmother out for meals, fishing and spending time with girlfriend and dog Sara.



Sandy has been in the background of JCY since a baby, growing up playing on chiller systems in the large 12,000SQFT pole shed JCY stores units in. Sandy started working at a young age doing simple tasks like sweeping, painting, organizing Copper fittings and other small tasks. In 2005 Sandy started his 4 year degree at Dunwoody College and graduated in 2007.

During his schooling their he also started his apprenticeship under his fathers supervision. The training consisted of installs of glycol piping in the field, building first chiller and assisting with Chiller service repairs. In 2006 he started learning the in and outs of breweries, and has been JCY’s brewery specialist since then. A challenge he took on was glycol piping a 30 bbl brewery by him self and completed that task in less than 20 day with 16 hour shifts.
