Introduction

Vahterus, a renowned Finnish company, is at the forefront of innovation in designing and manufacturing high-quality Plate & Shell Heat Exchangers. Their solutions are used across diverse industries such as energy, chemical, and food processing. With a reputation for precision engineering and sustainability, Vahterus has become a trusted partner for global clients seeking custom heat exchanger solutions that meet complex industrial requirements.

However, as Vahterus expanded its customer base, its reliance on outdated tools like Excel and a legacy Visual Basic application hindered their ability to efficiently manage offers and design heat exchangers. These inefficiencies prompted Vahterus to seek a technology partner capable of streamlining their workflows, modernizing their processes, and helping them scale effectively.

TECHVIFY was chosen for our technical expertise, flexibility in adapting to client needs, and proactive collaboration. Through our partnership, we delivered a robust web application for CRM and CPQ (Configure, Price, Quote) systems, enabling Vahterus to simplify their operations and exceed client expectations.

What're The Challenges We Faced?

As Vahterus’ operations expanded, they encountered several significant challenges:

Business Challenges 

01/ Outdated Systems
The company relied on Excel for managing sales offers and a legacy Visual Basic-based application for designing heat exchangers.
These tools could no longer support the increasing complexity and volume of operations.  

02/ Inefficient Workflows
Manually managing offers and design processes consumed excessive time and resources, leading to operational bottlenecks.

03/ Limited Scalability
The existing systems were unable to handle the growing customer base, leaving Vahterus at risk of losing opportunities.

04/ Development Setbacks
A previous development team had attempted to create a solution but failed to meet Vahterus’ requirements, resulting in the need for a complete system overhaul.

Discovery Phase

To ensure a thorough understanding of Vahterus’ needs, TECHVIFY employed a structured approach during the discovery phase:

Solution Design and Planning 

High-Level Solution Design

TECHVIFY designed a comprehensive web application to streamline Vahterus’ workflows, supporting:

01/ Offer Management
A CRM and CPQ system for creating and managing sales offers.

02/ Heat Exchanger Design
A modern interface to calculate and configure heat exchanger properties based on customer requirements.

Technology-Driven Workflows

The solution incorporated the following:

Front-end Technologies
A ReactJS-based interface with Tailwind CSS for a responsive, user-friendly experience.
Back-end Technologies
A robust NestJS framework integrated with Keycloak for authentication, PostgreSQL for data management, and Kubernetes for scalability.
Proprietary Logic Security
Using an embedding mechanism, we wrapped the client’s proprietary Visual Basic calculation logic to preserve their intellectual property and ensure secure integration into the new system.

Implementation and Challenges

Key Challenges

01/ Legacy System Integration
The client’s heat exchanger calculations were built on an old Visual Basic library, which they wanted to retain for security and accuracy reasons. Exporting the logic was not an option.

02/ Data Migration
The existing system contained a vast amount of data in varying formats, which needed to be securely migrated to the new platform while maintaining data integrity.

Overcoming Challenges

01/ Embedding Legacy Logic
To address the challenge of retaining proprietary calculation logic, we implemented an embedding mechanism that securely integrated the existing Visual Basic library into the new system. This allowed Vahterus to continue using their trusted algorithms without compromising on security or functionality.

02/ Data Migration Strategy
We wrote custom migration scripts to transform and transfer data from the old system to the new format, ensuring a seamless transition with zero data loss.
