Elevator modernization (or lift modernisation) is the process of upgrading the critical parts of the elevator in order for it to be able to handle new technology, have better performance, improve safety, and even give the aesthetics an up-to-date appeal
Most elevators are built to provide about 20 years of service, as long as service intervals specified and periodic maintenance/inspections by the manufacturer are followed. As the elevator ages and equipment become increasingly difficult to find or replace, along with code changes and deteriorating ride performance, a complete overhaul of the elevator may be suggested to the building owners.
A typical modernization consists of controller equipment, electrical wiring and buttons, position indicators and direction arrows, hoist machines and motors (including door operators), and sometimes door hanger tracks. Rarely are car slings, rails, or other heavy structures changed. The cost of an elevator modernization can range greatly depending on which type of equipment is to be installed.
Modernization can greatly improve operational reliability by replacing mechanical relays and contacts with solid-state electronics. Ride quality can be improved by replacing motor-generator-based drive designs with Variable-Voltage, Variable Frequency (VVVF) drives, providing near-seamless acceleration and deceleration. Passenger safety is also improved by updating systems and equipment to conform to current codes.

Passenger safety is also improved by updating systems and equipment (such as double brake system, unintended car movement protection device on the brake system etc.) to conform to current codes.
With CEP traction elevator modernization, we use the existing elevator structure while
upgrading the ride quality and reliability with state-of-the-art
components. Upgrade to a CEP closed loop door operator or a sophisticated, energy saving VVVF inverter.

Technical Data Sheet Toothpaste Grade Xanthan Gum
Xanthan gum is a microbial polysaccharide produced by fermentation of carbohydrate with Xanthomonas campestris, who is found in nature on the leaf surface of green vegetable,particularly the cabbage family. Xanthan Gum is yellowish white powder that is soluble in hot or cold water with a high viscosity even at low concentration.
Â
Benefit for toothpaste & oral care products
* High viscosity binding agent even in low concentration
* Suspend abrasives or pigment
* Low viscosity under shear stress and recover after shear stress removed,improve    Â
  production efficiency in mixing,pumping and filling
* Unique pseudoplasticity make toothpaste easy extrude from the tube
* Improve flavor release and stabilize the paste.
* Moisture retention

Xanthan Gum functionality in Oil Field
Xanthan Gum provides optimal viscosity characteristics Fluids in drilling, work-over,and completion operations. Optimum fluid performance is achieved when viscosity is minimized at high flow rates(such as at the drilling bit)and when viscosity is increased at low flow rates(as in the annular region),and under static conditions.
In additon to providing optimal viscosity characteristics, xanthan gum regains structure when circulation ceases.This property prevents setting of particles and is unique among hydrocolloid polymers commonly used in oil field applications.Sheer thinning viscosity characteristics with extended power behavior closely approximate the ideal viscosity profile for fluids used in the following applications.
Drilling fluids - The unique low shear rate viscosity of xanthan gum enhances the suspension properties of low colloid and bentonite-free fluid formulations.In addition,the pseudoplastic behavior of xanthan formulated systems provides optimum hydraulic efficiency of drilling fluids.It reduces pressure losses within the drill string,allowing maximum hydraulic power to be delivered to the bit.As a result,penetration rates can be increased.Other benefits from fluids formulated with xanthan gum include improved bottom-hole cleaning,increased cutting-carrying capacity under annular shear-rate conditions,and better separation efficiency in mechanical solids-control equipment.Because xanthan gum is compatible with most drilling fluid additives,it can be used in a wide variety of fluid formulations.These fluids include those with high pH,fresh water,and seawater,as well as electrolyte-inhibited systems containing dissolved electrolytes like calcium,potassium,and sodium.For special drilling applications,xanthan gum is also used to formulate stiff foams to improve stability and carrying capacity for drilled cuttings.
Workover and completion fluids - The pseudo-plastic properties of fluids formulated with xanthan gum make it a highly useful additive for workover and completion operations.Other key features include its compatibility with most field-formulated brines,its temperature and pH stability,and its lack of shear degradation.It provides superior solids suspension,friction reduction and minimal formation damage.
Hydraulic fracturing - Xanthan gum provides excellent visco-elastic properties for water-or acid-based hydraulic fracturing fluids.Its unique properties offer improved proppant suspension and maximum viscosity within the fracture without damaging fracture conductivity.
Gravel packing - Carrier fluids formulated with xanthan gum improve the stability and durability of gravel packs.In additon,these fluids allow efficient gravel placement in deviated wells,improved slurry transport at high gravel concentrations,and superior suspension at low polymer concentrations.At the same time,xanthan gum-based fluids protect formation permeability.
Â
Coiled tubing operations - Xanthan gum allows higher pumping rates by reducing friction-pressure losses in coiled tubing units.The increased flow rates allow solids to be removed more efficiently from the well.Field experience has indicated that xanthan gum can double the flow rates obtained with water and can ofen provide a 25-60% improvement over other polymers.
Enhanced oil recovery - Xanthan gum forms viscous,pseudoplastic fluids with superior mobility control for efficient fluid diaplacement in secondary and tertiary oil recovery processes.
