Dynamic balancing is standard practice for reducing bearing load and running noise. Dynamic balancing after a repair can increase the lifetime and efficiency of your rotating equipment.

Dynamic balancing is usually performed after the repair or manufacture of a component.

Balancing helps to:

• Reduce bearing load
• Reduce running noise
• Increase lifetime
• Improve quality
• Increase efficiency

We provide balancing service both at our workshops and on-site, using the very latest electronic precision balancing equipment.

• Workshop capacity ranges from 0.1 kg to 54,400 kg (0.2 lbs to 120,000 lbs) and to a maximum length of 9 meters (30 feet).
• Most components can be accommodated and balanced either to a specific tolerance or the applicable ISO or API specifications.

In some cases, a component requires a mandrel or modification to enable either mounting in the machine or attachment of correction weights. Our experienced engineers can design and manufacture the necessary parts, taking into account the required tolerance.

This service is not limited to items we manufacture or repair in-house. We perform dynamic balancing of production batches for many "Blue Chip" companies.

WRely on CoolCare for machining the parts of your rotating equipment. Our around-the-clock operations and extensive geographical coverage enables us to meet your needs.

Machining is of major importance in any reclamation process. This technique is used in various situations such as turning a shaft to size after welding or metal spraying, grinding a roller after hard chromium plating, or manufacturing a new component such as a gear when refurbishing a gearbox.

Our network of repair centers can carry out any machining process, including:

• Prep and finish
• Reverse engineering and remanufacture
• Turning
• Milling
• Grinding
• Vertical boring
• Horizontal boring
• Slotting
• Drilling
• CNC machining

We offer surface engineering and thermal spraying to ensure optimal performance. CoolCare can engineer the most suitable surface or coating to improve the performance of a component in a specific environment.

CoolCare can engineer the best-fitting surface or coating, based on years of experience, to find the optimum solution for you.

The BESCOTE® system helps select and apply the most suitable and cost-effective surface using either:

• Welding
• Electroplating
• Thermal spraying

BESCOTE® takes full account of the component's operating environment, its base material, working temperature, and any corrosive or erosive conditions as well as life cycles and costs. The BESCOTE® system can then be formulated for the application and fully defined and documented.

Hard chromium electroplating

Hard chromium produces a metal coating with a low friction coefficient thus ensuring hardness, wear resistance, and anti-corrosion properties (when used with nickel).

Mining equipment, rolls, and cylinders all benefit from reduced wear and anti-corrosion properties. Chromium has a low friction coefficient, making it an ideal coating for bearing journals, crankshafts, and hydraulic arms.

Adhesion and wear resistance remain good at high operating temperatures: the melting point of chromium is 1800ºC and the metal does not soften up to 400ºC. Chromium has the lowest friction band coefficient of commonly-used metals; other materials will only adhere to it with difficulty. When chromium is deposited correctly, it is impossible to detach the deposit from the base material.

Other key benefits of chromium:

• Surface hardness in excess of 62Rc
• Can be deposited in thicknesses ranging from 0.0005 to 0.040” (optimum range: 0.010”)

Nickel electroplating

Nickel can often be used underneath chromium to provide corrosion protection, or where heavy deposits are required. When used alone, nickel provides added protection for components operating in a highly corrosive atmosphere or in chemical solutions.

Our plating tanks are amongst the largest in the UK; we can accommodate the majority of industrial plating work.

Thermal spraying

CoolCare offers all forms of thermal spraying currently available and which can be used to restore component dimensions with materials similar to the original. Using recently-engineered coatings increases equipment life without distorting, cracking, or making the base material brittle.

We use various techniques:

• Combustion wire
• Electric arc
• Combustion powder
• Atmospheric plasma spraying (APS)
• High velocity oxygen fuel spraying (HVOF)

New Gigant solvent degreasing plant

• One of the biggest closed circuit degreasers outside the aerospace industry
• Uses trichloroethylene, a highly efficient and virtually emission-free cleaning medium
• Heated solvent vapor and spray wash used for cleaning, in order to remove contaminants from the most complex shapes
• Leaves no residue on the components

Accreditation

• Local Authority Integrated Pollution Prevention and Control Permit (LAIPPC)
• Site runs a BSI-approved 14001 Environmental Management System
• A Lloyds-approved plating facility
• Member of the Surface Engineering Association

Tank capacity: up to 8ft x 3ft x 12ft (2.5m x 0.9m x 3.6m)

All industries using mechanical machinery face a similar problem: machinery loses efficiency through wear during normal operation. Unit reconditioning by CoolCare improves performance and extends the lifetime of your equipment.

Thanks to our in-house precision fitting skills, we can recondition all types of process machinery such as engines, compressors, crushers, and gearboxes to their original state—or even to an enhanced level. We reclaim assembly components using a wide range of material replacement techniques, thereby both improving performance and extending equipment lifetime. The units are rebuilt with a special attention to details and then subjected to a thorough final inspection for quality assurance.

Reconditioning has many benefits over buying new machinery:

• Reconditioning can be faster than waiting for a replacement unit, particularly if the original is old.
• The new unit may not be a direct fit, and will be taken care of during installation and commissioning to ensure satisfactory operation

Surface engineering can often improve the wear characteristics of key components, thereby extending the unit's operational life.
