Frequently Asked Questions (FAQ)
Q1: What is the typical delivery time for this double-layer spiral coil evaporator?
A: Delivery time depends on the specific configuration and quantity. Standard models typically ship within 15–20 working days after order confirmation. Custom designs may require 25–35 days. Please contact us for an accurate lead time.
Q2: Can the evaporator be used for viscous fluids or those containing solids?
A: The spiral coil design is generally suitable for low to medium viscosity fluids. For fluids with high viscosity or suspended solids, we recommend a pre-filter or alternative design. Please provide your fluid properties for a feasibility assessment.
Q3: What is the maximum temperature of the steam used for cooling?
A: The unit is designed for a maximum operating temperature of 200°C. The steam temperature should not exceed this limit. For higher temperature applications, alternative materials or designs may be required.
Q4: Do you provide pressure testing certificates or material certificates?
A: Yes, we can provide material test certificates (MTC) for 304 stainless steel and pressure test reports. These are available upon request for an additional fee.
Q5: Is the evaporator suitable for food-grade applications?
A: 304 stainless steel is commonly used in food processing. Our standard finish is pickled and passivated, which meets basic hygiene requirements. For food-grade applications, we recommend optional electropolishing or mirror finish.
Q6: What are the dimensions and weight of a typical unit?
A: Dimensions vary based on the heat transfer area and coil configuration. A typical unit with a 10 m² heat transfer area may measure approximately 1.2 m in diameter and 2.5 m in height, with a weight around 800 kg. Please provide your required area for a specific drawing.
Q7: Can you customize the number of coil layers or the spacing between coils?
A: Yes, we offer customization of coil geometry, including layer count, tube diameter, and pitch, to optimize performance for your specific process conditions. Contact our engineering team for details.
Q8: What is the warranty policy for this product?
A: We provide a standard 12-month warranty against manufacturing defects from the date of shipment. Extended warranty options are available upon negotiation.
