ASERCOM CERTIFICATION

What is ASERCOM
ASERCOM (Association of European Refrigeration Component Manufacturers) promotes standards for safety and
performance ratings in the refrigeration industry. ASERCOM certification means that a compressor’s performance has
been determined to meet the specifications stated by it’s manufacturer.

How It Works
Manufacturer’s performance data for a particular compressor model and refrigerant are submitted to ASERCOM
for certification. To ensure objectivity, members of the certification committee are selected from competing
manufacturers. If the committee agrees with the submitted performance data that model is added to the certified list.

Performance Testing
Models from the certified list are regularly tested to verify perfomance. To ensure fairness, the compressor to be
tested is obtained from a distributor’s stock and tested at a competitor’s facility. If test results are not up to listed
specifications that model is removed from the certified list.

Frascold stands behind the quality, performance and reliability of

all of our products. We currently have 108 ASERCOM certified 9
models and more on the way. All of our compressors are run tested
at the factory and carry a standard 2 year warranty.

ATEX

The ATEX directive (2014/34/UE) is a certification for equipment and protective systems intended for use in
potentially explosive atmospheres, caused by the presence of gases or solid dust.
Our complete range of reciprocating and screw compressors (CX) is 100% certified in category 3G: devices or
protection systems that guarantee a very high level of protection Zone 2: an area where explosive atmosphere may
be present, but only in rare cases or for short periods.
The compressor lable includes the following ATEX assembly marking, usually placed on the wiring box:

CONTROL PROTECTION DEVICE

Discharge Temperature Cutoff

The discharge temperature in certain extreme conditions (such as high condensing temperatures, low evaporating
pressures or extremely high compression ratios), may reach values that can damage the compressor.
All V, Z and W series models are supplied with a safety device which, in combination with the electronic control
module, stops the compressor in the event that the discharge temperature exceed the set safety limit.

Electronic Safety Device to control lubrication

Frascold compressors in the V, Z and W series are supplied complete with an electronic pressure switch to control
lubrication. It monitors the differential pressure in the lubrication system and stops the compressor in the event of
any detected measurement that does not comply with the set safety values. The device is attached directly to the
compressor’s oil pump and does not require additional fittings.

INT69 ®
Standard protection equipment on A, B, D, Q and S series compressors consists of a chain of PTC or AMS thermistors
inserted in the electric motor stator and connected to the Kriwan INT69 ® electronic control module inside the
electrical box. The INT69® device is triggered and stops the compressor in the event of thermal overload due to electric
14
motor or mechanical issues.

INT69 ® Diagnose
Kriwan INT69 ® Diagnose protection device provides all of the protection of the INT69 ® with advanced
diagnostic and communication functions, allowing the compressor to be remotely monitored in real time via
modbus.
System conditions are monitored and the compressor is stopped in the event of incorrect functional parameters.
Detailed reporting allows quick identification of the cause of the malfunction. Stored data allows technicians to
accurately and quickly diagnose the past and present state of the cooling system, ensuring fast and cost-effective
servicing with short system downtime. Kriwan INT69® Diagnose is optional for all models from A to S series.

INT69 TML Diagnose

Kriwan INT69 TML Diagnose protection device. This unit provides all of the protection data logging and remote
monitoring capabilities of the INT69 ® and INT69 ® Diagnose but with the addition of lubrication protection.
Frascold V, Z and W series compressors come standard with INT69 TML ® Diagnose module.

CAPACITY REGULATION

Frascold reciprocating compressors capacity can be regulated with:

1. CAPACITY CONTROL (CC)
2. REDUCED SUCTION HEADS (RSH)
3. VARIABLE FREQUENCY DRIVE (VFD)

CAPACIT Y CONTROL (CC)

Frascold offers a standard capacity control feature. Available on request on 4, 6 and 8-cylinder compressors,
capacity may be adjusted by choking the heads in order to adapt the cooling capacity of the system to the actual
thermal demand. This reduces the start-up frequency and the stress on the compressor mechanics
and electric motor. Possible control stages:
4 Cylinder 6 Cylinder 8 Cylinder
2 Steps 50 / 100%
2 or 3 Steps 33 / 66 / 100% 50 / 66 / 100%

REDUCED SUCTION HEADS (RSH)

Frascold’s patented Reduced Suction Head (RSH) unloading technology represents a revolution in capacity
control for reciprocating compressors, avoiding problems caused by traditional unloading methods.
By allowing 50% gas flow to the unloaded cylinder head, RSH equipped systems: 15
• Can run unloaded indefinitely with no additional vibration, heat and stress to the motor vs. standard unloading methods.
• Match more accurately fluctuating cooling demand, saving a significant amount of energy over traditional unloading.

RSH unloading is available exclusively from Frascold and can be fitted to any Frascold reciprocating compressor
(2, 4, 6 and 8 cylinders). With more unloading steps and the ability to run unloaded indefinitely, RSH equipped
systems provide greater application flexiblity and energy costs can be significantly reduced. Fewer start-stop cycles
means increased service life, less down time and lower maintenance costs.

RSH Heads 2 Cylinder 4 Cylinder 6 Cylinder 8 Cylinder

1 50 / 100% 75 / 100% 83 / 100% 87.5 / 100%

2 50 / 75 / 100% 66 / 83 / 100% 75 / 87.5 / 100%

4 50 / 62.5 / 75 / 87.5 / 100%

VARIABLE FREQUENCY DRIVE VFD

All Frascold compressors are designed to be compatible with inverter technology. Inverters, also known as variable
frequency drives, can greatly improve performance and efficiency in many applications.

(For 400V motors in certain application conditions there might be a narrowing of the frequency range. Always
check on the Frascold Selection Software. For capacity data at the various frequencies see the Frascold
selection software FSS.3.)
