Alfa Laval Scrape Surface Heat Exchanger Contherm 6X9

Dual skid mount Alfa Laval Contherm Scrape Surface Heat Exchanger

Single-wall scraped-surface heat exchanger for flexible production of products with medium to extremely high viscosities.

More versatile: Contherm can handle products with or without particles and viscosities well in excess of 50,000 cP. It is the most versatile heat transfer solution on the market, with limitless
opportunities for full-line utilization in any production environment.

More flexible: Continuous scraping action makes Contherm easy to clean with relatively low hold-up volumes. It can flexibly transition from one product to the next, meaning minimal product loss and downtime.

More performance: Robust designs with multiple material options optimize heat transfer and product throughput, giving long-lasting mechanical performance.

More safety, more savings: Each vertical Contherm has its own hydraulic system, allowing for fast, easy and safe inspection as well as service with minimal labour costs.

Materials
The heating surface is made in 316 L stainless steel, honed to a very high finish on the inner surface. The scraping blades are made of Alfalon® III, Nylon and Teflon material. The seals are made of single carbon mechanical, carbon flushed / aseptic, hard face and hard face flushed / aseptic. Suitable materials will be selected for special applications.

Applications

The Contherm™ scraped-surface heat exchanger (SSHE) has found use within many different processes and applications for manufacturing food, chemicals, pharmaceuticals, cosmetics, health and beauty products, etc. It is particularly suited for processing viscous, heat sensitive, sticky or chunky (containing particulates) products that are to be pumped. It can be used in a broad range of processing environments, including: aseptic, heating, slush freezing, sterilization, cooling, pasteurization, crystallization and phase change.

Working principle
Product enters the cylinder through the lower product head and flows upwards through the cylinder. At the same time, the heating/cooling media travels in counter-current flow through the narrow annular channel between the heat transfer wall and the insulated jacket.

Rotating blades continuously remove product from the cylinder wall in order to ensure uniform transfer of heat between media and product. An optional coil in the annulus increases media velocity, adding to the heat transfer efficiency.

Product exits the cylinder through the upper tangential port. On start-up, air is completely purged from the Contherm. At the end of a processing run, the product can be drained or “chased-out” by water resulting in minimal product loss.

Scraper configuration, rotor diameter and rotor speed can be varied to suit the properties of the particular product flowing through the cylinder.

Flow Rate
The Contherm’s maximum flow rate is application specific and determined by the temperature program, nature of the product, and type of duty.

Production ready

Backed by warranty

We supply our used machinery fully serviced, production ready and backed by warranty. This is included in our initial quotation.

Every piece of equipment is put under a demanding inspection before delivery. Our inspection covers mechanical, electrical, pneumatic, and cosmetic checkpoints.
The unit is fully serviced to meet high mechanical, electrical, pneumatic, and cosmetic standards. Missing or damaged components are repaired or replaced.
Used machinery is backed by a standard 3-month warranty.

Terms and Conditions:
  • Warranty includes mechanical and electrical parts, but excludes electronic parts (for example, touch screens, servo drives and PLCs).
Our machinery is delivered compliant with the Australian AS 4024 Safety of Machinery Standards. Our engineering team is experienced in assessing machine safety and bringing machinery in line with AS 4024 by installing guards, ergonomic features and safety features like emergency stop controls.

Our machinery is delivered fully compliant with AS/NZS 3000 electrical standards.
Provide your product and our engineers will conduct a free trial run of your product. You can either be present, or we can send you video of the trial.

Terms and Conditions:
  • While this trial run is free of charge, any modifications or change parts are billable.
  • Trial runs must be booked in advance.
You are welcome to trial a machine in your plant for 2 weeks (you will be required to pay for transport of the machine and a refundable holding deposit).

Terms and Conditions:
  • Trial of machinery is subject to Process Plant Network confirming the machine is suitable for your product.
  • Get your product to market with minimal upfront investment.
  • Pay off the machinery with the revenue it generates.
  • Rentals are 100% tax deductible and not listed as an asset on your company’s asset register.
  • Minimise risk. It’s no secret that new product failure rates in the grocery sector are extremely high. With Rent to Buy, companies will not be left with paying off idle machinery assets if a project proves to be unsuccessful.
How it works:
  • Available for single machines or complete turnkey systems
  • Start producing immediately with a small down-payment of 2 months rental
  • 6 to 18 month rental periods available

We provide export crating, container loading and overseas freight services at additional cost.

For loose container load (LCL), we arrange an export crate using treated wood according to the machine size (to protect the machine from damage during transport) and crate the machine at our warehouse.

For full container load (FCL), we bring the empty container, load the equipment, and lash/secure them inside the container at our warehouse. We can then arrange either seafreight or airfreight to the customer's nominated destination sea/airports.

We usually arrange on the CFR (Cost and Freight) basis as per Incoterms.

Marine insurance, applicable local duties/taxes, custom clearance and delivery to customer's site in their destination country are to the customer's account.

We regularly provide this service for customers in New Zealand, the United Kingdom, the USA and Asia.
