A sample gives you something practical to evaluate before an order moves forward. Start with your drawing, an existing heater or a description of the application. We can discuss the appropriate sample route and the details you need to check.
A reference construction and a sample made to a defined specification serve different purposes. Agree what the sample needs to demonstrate before selecting the route.
Where a suitable existing construction is available, discuss a reference sample to examine its form, materials or connection arrangement. It may help narrow the design, but it does not confirm every requirement of your final heater. Sample availability, charges and delivery arrangements are agreed for the project.
For a defined requirement, discuss a sample based on the agreed dimensions, electrical duty, mounting and connections. Identify the features and operating conditions to evaluate. The sample scope, cost, preparation time, delivery and any revision work are confirmed before work begins.
A good sample review connects the physical heater to its intended equipment. Decide what acceptance looks like and record the results against the agreed specification.
Compare dimensions, mounting, bend or clearance requirements and lead exits with the installation. A heater can look suitable in isolation while fitting poorly around the actual equipment.
Examine the relevant materials, connections and finish against the sample specification. Separate visible features from electrical or thermal properties that require a suitable test or supporting document.
Where functional evaluation is required, agree the equipment, controls, conditions and acceptance criteria in advance. An unpowered visual sample and an operating evaluation answer different questions.
Identify the accepted sample and drawing revision, together with any changes still required. The written specification should remain clear enough to distinguish an approved feature from an unresolved point.
You can begin before every detail is fixed. A sketch, equipment photograph or existing part can help explain the task; the sample specification is then developed around the actual requirement.
Describe what needs heating, the target temperature, maximum exposure and available electrical supply. Include dimensions, mounting conditions, connections and the quantity you are considering. For a replacement, add the original part information and the reason for the change.
Define the proposed construction and the questions the sample should answer. Confirm the drawing or dimensional reference, evaluation conditions, requested documentation, sample charge and schedule. Any design deliverable or revision scope should be agreed explicitly.
Review the sample against the agreed criteria and identify any changes with their drawing references. Confirm whether the sample is accepted, whether another revision is needed, or whether the requirement should be reconsidered before an order is placed.
Email info@velheat.com with your drawing or application details, the features you want to evaluate and your preferred schedule. Sample fees and timing are confirmed for the individual project.
Send your drawing, operating conditions or the heating challenge you need to solve. Quantities are agreed for each custom project.
