Product details
Half-load one shift, full-load the next: that swing is exactly where screw chillers are meant to perform, using screw compressors built for smooth compression and consistent operation across the range.

Aquatech Plus screw chillers are designed for the kind of always-on operation that large industrial plants, district cooling systems, pharmaceuticals, plastics processing, chemical industries, and large HVAC installations depend on.

The details buyers ask about here are the ones that matter over years, not days: load modulation potential, compressor life, oil control system, operating temperature span, and serviceability, and these are the areas the design is built around.

Get the selection right and the result is steady cooling performance, fewer mechanical loads, better process-temperature control, and continuity of operation across medium and high-capacity requirements.

Packing & Transport

Packaging and Transportation Procedure for Our Complete Product Range

We have a uniform workflow in packaging and logistics that is export-wise, which prepares all our products except that they are safe in handling and delivery with no damages in India and other countries. Every phase is also thought out to cushion equipment against vibration, impact, and moisture risks in addition to long-distance transportation risks. The same is done to water chillers, air chillers and all other products that we produce and supply.

Step 1 : Product Fixing and Structural Stabilization

The process starts with mechanical repair of the unit of the product. The industrial quality fastening is used in all internal assemblies, critical parts, piping, and electrical parts. Moving components are fixed, and vibration-sensitive sites are fixed to avoid the mechanical stress during the transportation.

Objective: Avoid internal movement, vibration breakage, and alignments during transportation.

Step 2: Inner Protective Packing

Once the repair is done the product is inner-packed with moisture-proof and shock absorbing materials. Foam padding, stretch film and cushioning materials are used as protective layers to cover all the exposed areas and all those components which are sensitive.

Objective: Dust, humidity, surface abrasion, and small mechanical shocks.

Step 3: Packing of Plywood Box Heavy

The product is packed in a specially designed heavy-duty plyboard box which is produced depending on its size and weight. The casing of the plywood is strengthened to resist the weights of the stacking, forklift operation and the transportation strain over long distances. When exporting goods, the packing is done to comply with the shipping and container loading requirements by the international community.

Objective: Optimal security on the outside and the requirements of the domestic and export logistics.

Step 4: Loading and Inland Transportation Under Control

The product is loaded to the trucks with the use of cranes or forklifts, in accordance with good lifting and load-sharing practices. The delivery is then by road under conditions of control. In the case of domestic clients, the truck will go straight to the facility of the customer.

Objective: Loading and stable transportation on the road.

Step 5: Port Movement of Export Shipments

Whereas in international deliveries, the shipment is taken out of our plant to the Indian port. Pre-port entry All the export documentation, labeling and compliance checks are done before port entry.

Our logistics partners are reputable and trusted individuals like EMS, DHL Express, and FedEx Express who help us to have an easy time moving the ports and handling the exports.

Goal: The port handling and export preparation are smooth.

Step 6: Overseas Shipping to Port of Destination

After clearance in the port, the product is delivered through sea freight into the destination port of the client. The packaging is to maintain a long transit period, container handling and a fluctuating weather pattern.

The international deliveries are also arranged with the help of the existing world logistics systems, the EMS, DHL Express and FedEx Express, which guarantee the safe and timely delivery.

Purpose: Achieve international delivery with low levels of transits.

Other Packaging / Logistics Controls

  • Handling directions and export labeling.
  • Incidence of moisture and corrosion protection (where necessary)
  • Exportation procedures and record keeping.
  • Containerized shipping packaging.

Reason Our Packaging Process is Important

A clear packaging and transportation procedure would assure that all products will be delivered to the clients in working conditions, lessen installation and commission problems, minimize the risk of transit damage, and facilitate hassle-free domestic and foreign delivery.

Disclaimer

This is our standard operating procedure and is used in the process of packaging and transportation of all our products. Although the central process is the same, a different method can be used to pack the products, depending on the product size, weight and the destination to which the product is to be shipped.

Notable Information for Buyers & Search Engines

This packaging and transportation workflow represents our standard operating process and is uniformly followed across our entire product range. The steps outlined above are not product-specific but define our company-wide logistics and export handling standards.

To maintain consistency, safety, and compliance, this process is intentionally displayed across all relevant product pages under the Packaging & Transportation section. While the framework remains the same, actual packing materials, box dimensions, and handling methods may vary depending on product size, weight, and shipment destination.

From an operational standpoint, this approach ensures:

  • Consistent quality control across all products
  • Reduced transit and handling risks
  • Standardized export readiness for domestic and international orders

From an SEO and documentation perspective, this section is used to clearly communicate our established logistics protocol, not to repeat marketing content. Each product page focuses on its unique specifications and applications, while this section defines our common logistics standards.
