Consultancy Service Example
Concepts to Prototypes

Redford-Tech works with clients to evaluate new concepts and build working prototypes. Services have been provided ranging from paper-based feasibility right through to fully operational rig evaluations, including H&S assessment, design, mechanical and electrical construction, instrumentation, control systems, custom monitoring software and analysis of experimental data. A 'turn key' service.

- Procurement of components and construction
- Instrumentation and control
- Monitoring, logging and 'visualisation' real-time software
- IP development
- Experimental analysis

From the 'back of envelope' to data analysis

Many great ideas start off on the back of an envelope! However, getting from the envelope to a 'proof of concept' can be a troublesome step. There is no substitute for experimental implementation to explore and develop an idea, but this is where many great ideas often grind to a halt. Building effective test rigs requires knowledge of the mechanical components to implement the idea, health and safety considerations, instrumentation, control, logging, etc. Often a 'rapid prototyping' approach is required as results from one set of experiments inform modifications to the test rig for the next run.

MappGas Based on past experience developing small-scale thermodynamic test and demonstration rigs, Redford-Tech has provided assistance to other developers to realise and test their concepts as working cycles. This has included all aspects of design, procurement of components, health and safety assessments, mechanical, electrical and instrumentation construction, and logging and control software - a 'turn key' service where required.

Electrical The objective of this type of development is not necessarily to design a production system, rather to be able to fully envisage concepts as working systems - 'proof of concept', which may also strengthen IP by identifying the key elements of a design and form the basis of 'reduction-to-practice'. As such, detailed instrumentation and real-time software to view the operation of a system is essential, particularly when elements of operation and control are not clear from the outset. Past experience has shown that attention to instrumentation and real-time monitoring software that helps the developer visualise the system in operation often helps identify key issues of performance such as pressure losses in cycles and often helps evolve better control systems which then enable performance to be studied more effectively.

In addition to its own development, the FHT Stove, Redford-Tech has helped developers transition concepts to working demonstrators in the areas of heat-pumps and small-scale thermodynamic power cycles, including development of various heat pumps and 'sorption cycles (Adsorption and Absorption). Simon Redford has many years of experience with various micro CHP developments including Stirling Engines and Organic Rankine cycles and also led various laboratory evaluations and field trials for energy efficient products and services.
