Danfoss sight glasses are designed to accurately indicate the presence of moisture in refrigeration and air-conditioning systems. When system moisture content rises above permissible levels, the “dry/green” indicator will change to yellow indicating a “wet” system. The indication of dangerous moisture levels is essential in helping prevent the formation of harmful acids which are detrimental to the system. Danfoss offers two types of sight glasses; inline and vessel mount. Inline sight glass, type SGP N is used in the system’s liquid line to indicate both the condition and moisture content of the refrigerant. They incorporate an indicator which changes color dependent on the moisture content. Type SGP N is recommended for HFC refrigerants. Vessel sight glasses, type SGP RN are specially designed to be mounted directly on either a receiver or the compressor crankcase to indicate liquid level. Type SGP RN are available with a refrigerant moisture indicator which can be used with all fluorinated refrigerants
Danfoss DCL/DCB filter driers offer industry leading system protection. These driers use a mixture of molecular sieve and activated alumina to both adsorb system moisture and capture acid and prevent solid contaminants from entering the system. Moisture can clog an expansion device with ice, reducing system efficiency, or can form acids which damage the compressor and other components. Solid contaminants can clog expansion devices and wear compressors prematurely. Selecting a Filter Drier For aftermarket service, most contractors choose this blend of molecular sieve and activated alumina for both high moisture capacity and acid adsorption capacity. Type DAS are used in the suction line to clean up refrigeration and AC systems with fluorinated refrigerants after a compressor burn-out. The solid core adsorbs harmful acids as well as moisture to protect the compressor from premature failure. Danfoss filter driers function as simple drop-in replacements for most driers sold in the aftermarket or installed on equipment by manufacturers. All Danfoss filter driers are constructed with a solid core design to maximize moisture removal while minimizing pressure drop. Other product features and benefits are depicted in the pictures below.

Known for their legendary durability, Maneurop® reciprocating compressors from Danfoss are specially designed for applications with a wide range of operating conditions. Maneurop® MT and MTZ series compressors are of the hermetic reciprocating type and are designed for medium and high evaporating temperature applications. The MT series is designed for use with the "traditional" R-22 refrigerant, using Danfoss mineral oil 160P as lubricant. The MT series can also be applied with several R-22 based refrigerant blends (substitute refrigerants), using160 ABM alkylbenzene as lubricant. The MTZ series is specifically designed for use with the HFC refrigerants R-407A/C/F, R-134a, R-404A, and R-507A, using 160PZ polyester oil. MT and MTZ compressors have a large internal free volume that protects against the risk of liquid hammering when liquid refrigerant enters the compressor. MT and MTZ compressors are available in 16 different models with capacity ranging from 1.5 to 13 Tons
Danfoss Residential and Light Commercial Air Conditioning Scroll Compressors install quickly and easily. These compressors feature a design that minimizes internal parts, decreasing overall weight, and significantly reducing the sound produced during operation. With a bolt pattern and liquid and suction line connections that match up almost identically to those of other major scroll compressor manufacturers, Danfoss scroll compressors can be used to replace compressors made by both Danfoss and other companies.
Crankcase pressure regulator type KVL is fitted in the suction line ahead of the compressor. The KVL protects the compressor motor against overload during start-up after long standstill periods or after defrost periods (High pressure evaporator)
KVC hot gas bypass regulator are used to adapt compressor capacity to actual evaporator load by supplying a replacement capacity in form of hot / cool gas. It is installed in a bypass line between the high and low pressure sides of the refrigeration system and is designed for direct gas injection into the suction line.
KVP evaporator pressure regulator are mounted in the suction line of refrigeration and air conditioning systems. They are used to maintain a constant pressure corresponding to a constant temperature on the evaporator. They also protect against too low an evaporating pressure by throttling down when pressure falls below the set value. They are also used to differentiate the evaporating pressures in two or more evaporators in systems with one compressor.
The UT thermostat is a temperature-controlled electric switch with stainless steel (18/8) or copper capillary and sensor. The temperature can be set easily and accurately using the large knob on the front of the thermostat. The temperature must be set to correspond to the required mean temperature.
T Pressure switches incorporate a pressure controlled, single-pole change over swich where the contact position depends on the pressure in the connection port and the set value. The RT series consists of pressure switches, differential pressure switches and pressure switches for neutral zone regulation, all for general use within the industrial and marine segments. The series also covers safety pressure switches dedicated for steam boiler plants. For installations in which operation is particularly critical from safety and economic points of view, the use of fail-safe pressure switches is recommended. The use of gold-plated contacts is also recommended in such installations, provided operation involves only a few switching cycles or signal currents and voltages.

In a Danfoss SM / SY / SZ scroll compressor, the compression is performed by two scroll elements located in the upper part of the compressor. Suction gas enters the compressor at the suction connection. As all of the gas flows around and through the electrical motor, thus ensuring complete motor cooling in all applications, oil droplets separate and fall into the oil sump. After exiting the electrical motor, the gas enters the scroll elements where compression takes place. Ultimately, the discharge gas leaves the compressor at the discharge connection.

The valves have one-piece wire seal cap to prevent unintentional cap removal or tampering between services.
Thermostatic expansion valves regulate the injection of refrigerant liquid into evaporators. Injection is controlled by the refrigerant superheat. Therefore the valves are especially suitable for liquid injection in ”dry“ evaporators where the superheat at the evaporator outlet is proportional to the evaporator load.
The KP pressure switches can be used as safety switches against too low a suction pressure and / or too high a discharge pressure in refrigeration and air conditioning systems. They can also be used to start / stop compressors and fans for air-cooled condensers. They are available in both single and dual versions and include a single pole double throw (SPDT) switch.
