MECO - A worldwide leader in water purification

Retrofit/Upgrades

The Fountain of Youth for Water Purification Equipment.

The exacting standards of producing critical utilities demand that your plant always run at its optimal capabilities. A task that gets more and more difficult as it ages. Normal wear and tear, along with technological advancements, have led companies to rely on MECO for our retrofit and upgrade services.

New Life for Older Equipment.

MECO extends the life of distillers and other water treatment systems by offering control system upgrades and refurbishments. The benefits of this service include:

• An extension of the distiller's life, which reduces the capital outlay for new equipment.
• Improved operation of the plant through more accurate operating control, higher equipment reliability and reduced maintenance.
• An updated system to meet higher quality assurance and validation standards.

Consistency With Controls.

MECO offers the following upgrades:

• Lube Lock Seal System Upgrade
• Compressor Lube Oil System Upgrade
• Exhaust Filter Upgrade
• Vapor Compression Still Controls Retrofit
• Remote Monitoring Upgrade

Other upgrades are available upon request. To order these upgrades or request a quote, please contact MECO MASTERsupport™ at 1-800-421-1798 or online at the MASTERsupport™ Online Service Center.

Lube Lock Seal System Upgrade

The MECO Lube Lock Seal System (LLSS) greatly reduces the chance of leakage. It has been engineered to utilize straight thread O-ring connections on all joints instead tapered pipe thread connections. The use of replaceable O-Rings for sealing rather than the interference and challenges of formed threads provides a much tighter, more reliable, maintenance-free seal. Systems can be disassembled and reassembled numerous times with no additional make-up required. And all existing equipment can be upgraded with this new system.

Compressor Lube Oil System Upgrade

This upgrade significantly reduces the chance for leakage at the compressor's joints. Straight thread, O-ring connections per SAE J514 are utilized on all joints instead of standard tapered pipe thread connections. The SAE connections depend on simple, replaceable O-rings for sealing rather than the interference of perfectly formed threads. Systems can be disassembled and reassembled numerous times with no additional make-up required.

Exhaust Filter Upgrade

Pressurized lube oil systems have the tendency to produce and emit a mist in the form of an oil vapor from the vent cap installed in the compressor housing. For our larger compressors, model D6/D7 used on MECO 2900 gph or larger units, we have developed a method to capture these vent fumes/mist by installing a specially designed cartridge filter. Eliminates Oil Exhaust Fumes The cartridge filter eliminates the oil exhaust fumes/mist from the atmosphere by capturing the visible oil vapor and re-depositing the liquids back to the oil tank. This upgrade is currently installed on all new MECO units and can be easily adapted to older units in the field. Minor modifications to the present lube oil piping have to be made in order to incorporate the new connections.
