GEA provide compressor conversion kits for any screw
compressor package. Each GEA Grasso conversion kit (GGCK) is
supplied complete with a new GEA screw compressor and other
standard components.
Each conversion kit is designed specifically to suit the existing
package unit in order to minimize any on-site modifications.
This enables fixed prices to be offered with short down times
and a compressor manufacturer’s warranty is included.
The existing drive motor, oil separator and oil cooling system
are reused. The existing control system may also be re-used
although GEA’s latest control system can also be supplied.
Benefits of a GGCK
• Future proof upgrade at a fixed price. Budget without
surprises
• New, high quality, state of the art GEA Screw Compressor.
Low noise and vibration level due to 4/6 rotor profile
• Optimize system capacity and energy efficiency. Reduced
operating cost.
• Fully supported by GEA with standard warranty for new GEA
components
• Up to 66% longer interval between major overhauls. Reduced
downtime and maintenance cost
• Re-use main components, quicker and less expensive than
replacing the complete compressor package. No need for
machine room alterations.
• Possible to re-use existing control system or upgrade to latest
GEA OmniTM control system
• Fully engineered GEA solution Less engineering time for you
Update your existing screw compressor packages
Provided your package is in good condition, with good access in the plant room
and flexible control system we can select a Grasso equivalent compressor to suit
existing frame, fit a new oil system and pump and commission. In most cases we
have been able to reuse the existing motor with the use of a new drive coupling.
Full production drawing and P&ID provided with each project.

GEA OmniTM Retrofit Panel
Upgrade your compressor control – GEA now offers a
standardised retrofit solution for industrial screw and piston
compressors, ensuring operators’ continued success. GEA
Omni™ Retrofit Panels have already proved their worth with
compressor packages from many manufacturers including
Mycom, Howden, Frick, Sabroe and Stal.
Easy to connect – The GEA Omni™ Retrofit Panel includes
hardware designed to allow the connection of different types
of compressor sensors, motor current sensors and solenoid
coil voltages. This reduces the number of loose shipped items
to a minimum, thus simplifying and reducing installation time.
Compressor-specific electrical drawings and preconfigured
software are provided on a GEA USB drive.
GEA now offers its market leading OmniTM control system as a retrofit panel solution for industrial screw and piston compressor packages

GEA PR-OLEO® Refrigeration Oil
Stock Available
2-stage hydrocracked lubricants formulated specifically for use in ammonia refrigeration systems with either reciprocating
or screw compressors. Utilizing ultra-pure base oils and additives, PR-OLEO® lubricants offer significant advantages over
common ammonia refrigeration oils and contribute to more efficient plant operation.
There are two versions of PR-OLEO® available:
• PR-OLEO® C-MH68A – For use in new applications or when replacing other lubricants, contains seal conditioner.
• PR-OLEO® C-MH68A-FG – NSF H1 registered Food Grade for use in new applications where food safety is of critical
importance.
Benefits of PR-OLEO®
• Ultra-pure base oil, very low oil carryover rates and excellent low-temperature fluidity all contribute to improved heat
transfer in evaporators – Reduced energy costs
• Improved heat transfer means higher evaporating temperatures and lower compressor operating temperatures – Better
system efficiency
• Long-lasting formulation combined with very low oil carryover rates leads to reduced wear of compressor parts, less inter-
ventions and increased safety – Lower maintenance costs
• Suitable for both piston and screw compressors – Reduced stock requirements
• Compatibility with other ammonia refrigeration oils – Easy to upgrade
• The NSF H1 registered Food Grade available – Improved end- product safety
PR-OLEO® premium-quality ammonia refrigeration oils are highly refined
Page | 66 · RUBRIC
PR-OLEO® C-MH68A-FG is registered by NSF International, Category
Code H1 (incidental food contact), NSF Registration Number 155239.
